Send email with tracked link to a server using Mailscanner. Expected Behavior. Email should go through without without links altered and marked. The reason getmail doesn't deliver directly to maildrop is because I'm aiming to use mailscanner for anti-spam and anti-virus.

Even the presence of an administration panel on a system, because they take over the systems in strange and non-standard ways, making it difficult or even impossible for actual system administrators to manage the servers normally , and tend to indicate low-quality questions from users with insufficient knowledge for this site.

Consequently mailscanner rejects message as malformed. Example: joe mail. After downgrading to 5. Great app!! Re: Mailscanner 5. The following updates will be applied on fap-mta Doing some research.
MailScanner is going to need to workaround the violation. However, If we will get mail from outside Groupwise that has DSN enabled, it will be denied as undeliverable to groupwise-name. We are running MailScanner 5. If I filter the log on DSN, I see 62 entries in today's log both inbound and outbound to and from GWIA to MailScanner with the correct email address, no "groupwise-" appended and when I look at the properties of the email I sent today, it says "Transferred" as usual.
Both our MailScanner and GW environments are upgrades from old origins though, so there may be things in the config files I have forgotten.

For server level systems such as email gateways, which is what MailScanner is, you really should not install a GUI with your operating system unless it is specifically designed for use with MailScanner such as Mailborder or Baruwa. In short, if MailScanner does not need something to function, then you should not install it. An internet connection and root level privileges are required on the server on which MailScanner is being installed.
Ensure that the system's package management feature is working before attempting to install MailScanner as these are used by the installation scripts to install the required software. Examples: Yum, Apt, Zypper. Each installation script will check for basic requirements to MailScanner to operate and then attempt to install any missing components via your server's package management system.
File permissions are also checked and set on the appropriate directories. Once you have completed the installation of MailScanner, you will need to edit the configuration files. The primary files you need to pay attention to are:. This is useful if you are wary about your users sending encrypted messages to your competition. This can be a ruleset so you can block encrypted message to certain domains.
Should unencrypted messages be blocked? This could be used to ensure all your users send messages outside your company encrypted to avoid snooping of mail to your business partners. When you bounce a spam message back to the sender, do you want to encapsulate it in another message, rather like the "attachment" option when delivering spam to the original recipient? NOTE: If you enable this option, be sure to whitelist your local server ie.
Many naive spammers send out the same message to lots of people. These messages are very likely to have roughly the same SpamAssassin score. For extra speed, cache the SpamAssassin results for the messages being processed so that you only call SpamAssassin once for all of the messages. Normally, you can still get the filenames out of a password-protected archive, despite the encryption.
So by default filename checks are still done on these files. However, some people want to suppress this checking as they allow a few people to receive password-protected archives that contain things such as. This option can be used to suppress filename checks inside password-protected archives. If the message sender is on any of the Spam Lists, do you still want to do the SpamAssassin checks? Setting this to "no" will reduce the load on your server, but will stop the High Scoring Spam Actions from ever happening.
Enable this feature if you have more then one Mailscanner installation or you have a trust relationship with another Mailscanner user. For this to work you need to use the same value for "Watermark Header", and have the same "Watermark Secret". This could be achieved by using a ruleset. This feature skips Spam Checks if the Watermark is trusted. The trust only works between servers so will not apply to replies to emails. If the Watermark has expired or is invalid then the message is processed as normal.
Check Watermarks With No Sender. Do you want to check watermarks? There are now sets of signatures available from places such as www. Some of these signatures rely on being passed the whole message as one file. By setting this option to "yes", each entire message is written out to the scanning area, thus enabling these signatures to work reliably. It has a slight speed impact but is worth it for the extra spam-spotting ability.
This option cannot be the filename of a ruleset, it must be "yes" or "no". ClamAVModule only: set limits when scanning for viruses. The maximum recursion level of archives, The maximum number of files per batch, The maximum file of each file, The maximum compression ratio of archive.
Clamd only: configuration options for using the clamd daemon. The port to use when communicating with clamd via TCP connection 2. The Socket, or IP to use for communicating with the clamd Daemon. The ClamD Lock file should be created by clamd init script in most cases. If it is not then the entry should be blank. If MailScanner is running on a system with more then 1 CPU core or more than 1 CPU then you can set "Clamd Use Threads" to "yes" to speed up the scanning, otherwise there is no advantage and it should be set to "no".
None of these options can be the filenames of rulesets, they must be just simple values. Allowed Values end. If an attachment triggered a content check, but there was nothing else wrong with the message, do you want to modify the subject line? This makes filtering in Outlook very easy.
This is the text to add to the start of the subject if the "Content Modify Subject" option is set. You might want to change this so your users can see at a glance whether it just was just the content that MailScanner rejected. This option interacts with the "Allow Tags" options above like this: Allow Tags Convert Danger This makes the HTML harmless, while still allowing your users to see the text content of the messages.
Note that all graphical content will be removed. This can also be the filename of a ruleset, so you can make this apply only to specific users or domains. Do you want to convert all HTML messages into plain text? This is very useful for users who are children or are easily offended by nasty things like pornographic spam. This can also be the filename of a ruleset, so you can switch this feature on and off for particular users or domains.
This file lists all the countries that use 2nd-level and 3rd-level domain names to classify distinct types of website within their country. This cannot be the name of a ruleset, it is just a simple setting. Where to put the code for your "Custom Functions".
No code in this directory should be over-written by the installation or upgrade process. All files starting with ". How long should the custom spam scanner take to run? If it takes more seconds than this, then it should be considered to have crashed and should be killed. This stops denial-of-service attacks.
Custom Spam Scanner Timeout History. See the previous comment for more information. The default values of 10 and 20 mean that 10 timeouts in any sequence of 20 attempts will trigger the behaviour described above, until the next periodic restart see "Restart Every". Do you want to scan the messages for potentially dangerous content?
If you wish to read settings from a database or any other DBI-compatible data source, then this value should be set to the DBI data source name. This value is required for all of the database functions to work; if it is not supplied or is invalid, then all of the database functions will be disabled. See the Perl DBI documentation for all available options.
Set Debug to "yes" to stop it running as a daemon and just process one batch of messages and then exit. In the "Filename Rules" and "Filetype Rules" rule files, you can say that you want particular attachment names or types to be "disarmed" by being renamed. See the sample files for examples of this. The "rename" rules in filetype. In filename. They can work just like the filetype rules. For example, a rule starting rename to. The "rename" rules change the filename of the attachment as described above, so that either a the user cannot simply double-click on the attachment, but must save it then rename it back to its original name; only then can they double-click on the file.
OR b the action taken when the user double-clicks on the file will be changed. This provides a simple safeguard so that users have to consciously think about what they are doing, and do not accidentally take actions they would probably regret.
In some situations this is better than just denying the file completely, as the user can still see the attachment they were sent. Setting this to yes means that spam found in the blacklist is treated as "High Scoring Spam" in the "Spam Actions" section below. Setting it to no means that it will be treated as "normal" spam. Deleted Bad Content Message Report. Set where to find the message text sent to users when one of their attachments has been deleted from a message.
These can also be the filenames of rulesets. Deleted Bad Filename Message Report. Do you want to deliver messages once they have been cleaned of any viruses? By making this a ruleset, you can re-create the "Deliver From Local" facility of previous versions. Should I attempt to disinfect infected attachments and then deliver the clean ones. So the default has been changed to "no" as it gives a significant performance improvement. When attempting delivery of outgoing messages, should we do it in the background or wait for it to complete?
The danger of doing it in the background is that the machine load goes ever upwards while all the slow sendmail processes run to completion. However, running it in the foreground may cause the mail server to run too slowly. Some versions of Microsoft Outlook generate unparsable Rich Text format attachments. Do we want to deliver these bad attachments anyway? Setting this to yes introduces the slight risk of a virus getting through, but if you have a lot of troubled Outlook users you might need to do this.
We are working on a replacement for the TNEF decoder. Allowed Values queue. Attempt immediate delivery of messages, or just place them in the outgoing queue for the MTA to deliver when it wants to? For example, you could use a ruleset here so that messages coming to you are immediately delivered, while messages going to any other site are just placed in the queue in case the remote delivery is very slow. Deny any attachment MIME types matching any of the patterns listed here.
Deny any attachment filenames matching any of the patterns listed here. Deny any attachment filetypes matching any of the patterns listed here. This is the text to add to the start of the subject if the "Disarmed Modify Subject" option is set.
Set where to find the message text sent to users explaining about the attached disinfected documents. If any of these headers exist, then the message is actually a reply and so we may not want to sign it with an HTML signature. Plain text sig- natures will still apply, but HTML signatures, which may include an image, will not. By default, this feature is disabled by specifying no header names.
This should be a space or comma-separated list of header names. You can use this ruleset to enable the "bounce" Spam Action. Beware that many sites will automatically delete the bounce messages created by using this option unless you have agreed this with them in advance. If you enable this, be prepared to handle the irate responses from people to whom you are essentially sending more spam! This is the name of the Envelope From header controlled by the option above.
This is the name of the Envelope To header controlled by the option above. This should be "yes" unless the scanner you are using Sophos, McAfee has the facility built-in. However, if you set it to "no", then the filenames within the TNEF attachment will not be checked against the filename rules. Where the "file" command is installed.
This is used for checking the content type of files, regardless of their filename. To disable Filetype checking, set this value to blank. If an attachment triggered a filename check, but there was nothing else wrong with the message, do you want to modify the subject line?
Set where to find the attachment filename ruleset. The structure of this file is explained elsewhere, but it is used to accept or reject file attachments based on their name, regardless of whether they are infected or not. This can also point to a ruleset, but the ruleset filename must end in ". This is the text to add to the start of the subject if the "Filename Modify Subject" option is set.
You might want to change this so your users can see at a glance whether it just was just the filename that MailScanner rejected. The maximum length of time the "file" command is allowed to run for 1 batch of messages in seconds. Set where to find the attachment filetype ruleset.
The structure of this file is explained elsewhere, but it is used to accept or reject file attachments based on their content as determined by the "file" command, regardless of whether they are infected or not. Find zip archives by filename or by file contents? Finding them by content is a far more reliable way of finding them, but it does mean that you cannot tell your users to avoid zip file checking by renaming the file from ". Only set this to no i.
Note this does not affect virus checking, but it will affect all the other checks done on the contents of the zip file. Do you want to check for "Phishing" attacks? These are attacks that look like a genuine email message from your bank, which contain a link to click on to take you to the web site where you will be asked to type in personal information such as your account number or credit card details.
Except it is not the real bank's web site at all, it is a very good copy of it run by thieves who want to steal your personal information or credit card details. These can be spotted because the real address of the link in the message is not the same as the text that appears to be the link. Note: This does cause extra load, particularly on systems receiving lots of spam such as secondary MX hosts. A few viruses store their infected data in UU-encoded files, to try to catch out virus scanners.
This rarely succeeds at all. Setting this option to yes means that you can apply filename and filetype checks to the contents of UU-encoded files. This may occasionally be useful, in which case you should set to yes. Do the spam checks first, or the MCP checks first? This cannot be the filename of a ruleset, only a fixed value. Options specific to F-Protd-6 Anti-Virus This is the port number used by the local fpscand daemon. This option cannot be the filename of a ruleset, it must be a number.
Where the "gunzip" command is installed. This is used for expanding. To disable gzipped file checking, set this value to blank and the timeout to 0. The maximum length of time the "gunzip" command is allowed to run to expand 1 attachment file in seconds. Hide the directory path from all virus scanner reports sent to users.
The extra directory paths give away information about your setup, and tend to just confuse users. Hide Incoming Work Dir in Notices. Hide the directory path from all the system administrator notices. The extra directory paths give away information about your setup, and tend to just confuse users but are still useful for local sys admins. If a phishing fraud is detected, do you want to highlight the tag with a message stating that the link may be to a fraudulent web site.
This can also be the filename of a ruleeset. This is just like the "Spam Actions" option above, except that it applies when the score from SpamAssassin is higher than the "High SpamAssassin Score" value. You need to specify "deliver" as well for the message to reach the original recipient.
This means the user has to take an extra step to open the spam, and stops "web bugs" very effectively. They can then take action to request retrieval of the original message if they think it was not spam. This is very useful if you just forward the message to a new address and don't use the "deliver" action, as otherwise the list of the original recipients may be lost. This can be used to implement any custom action you require. This means that you can forward messages to email addresses which show the original recipients of the message, which could be very useful when delivering into spam archive management systems.
The default value I have set here enables Thunderbird to automatically handle spam when set to trust the "SpamAssassin" headers. This can also be the filename of a ruleset, in which case the filename must end in ". High Scoring Spam Modify Subject. You may want to use this to deliver moderate scores, while deleting very high scoring messsages.
Name of this host, or a name like "The MailScanner" if you want to hide the real hostname. It is used in the Help Desk note contained in the virus warnings sent to users. Setting this adds the MailScanner message id number to a header in the message. This is a list of filenames or parts of filenames that may appear in the filename of a web bug URL. They are only checked in the filename, not any directories or hostnames in the URL of the possible web bug.
If it appears, then the web bug is assumed to be a harmless "spacer" for page layout purposes and not a real web bug at all. Note: Use this with care, as spammers may use this to circumvent the web bug trap. It is disabled by default because of this problem. Spammers have learnt that they can get their message through by sending a message with lots of recipients, one of which chooses to whitelist everything coming to them, including the spammer.
So if a message arrives with more than this number of recipients, ignore the "Is Definitely Not Spam" whitelist. Normally, SpamAssassin skips over all non-text attachments and does not scan them for indications that the message is spam. This setting over-rides that behaviour, telling SpamAssassin to scan all attachments regardless of type.
This can be very useful for spotting rude and derogatory content in Microsoft Word documents, for example. However, it does slightly slow SpamAssassin and so is disabled by default. Setting this to "yes" will have no effect without a small patch to the SpamAssassin code. That web page will explain in detail how to apply the patch. Include Scanner Name In Reports. Include the name of the virus scanner in each of the scanner reports. This also includes the translation of "MailScanner" in each of the report lines resulting from one of MailScanner's own checks such as filename, filetype or dangerous HTML content.
Very useful if you use several virus scanners, but a bad idea if you don't want to let your customers know which scanners you use. Do you want to include the numerical scores in the detailed SpamAssassin report, or just list the names of the scores. Set location of incoming mail queue This can be any one of 1. The name of a file containing a list of directory names, which can in turn contain wildcards.
I will find the subdirectories automatically. Set where to unpack incoming messages before scanning them This can completely safely use tmpfs or a ramdisk, which will give you a significant performance improvement. Typical use: external helper programs of virus scanners notably ClamAV , like unpackers. Use with care, you may well open security holes. If you want to create the temporary working files so they are owned by a user other than the "Run As User" setting at the top of this file, you can change that here.
Note: If the "Run As User" is not "root" you cannot change the user but may still be able to change the group, if the "Run As User" is a member of both of the groups "Run As Group" and "Incoming Work Group" Note: If the "Run As User" is "root" or not set at all and you are using the "clamd" virus scanner AND clamd is not running as root, then this must be set to the group clamd is using from your clamd.
Add this extra header to all mail as it is processed. The contents is set by "Information Header Value" and is intended for you to be able to insert a help URL for your users. If you don't want an information header at all, just comment out this setting or set it to be blank. Set the "Information Header" to this value. Set where to find the HTML and text versions that will be inserted at the top of messages that have had viruses removed from them.
If you use the 'attachment' Spam Action or High Scoring Spam Action then this is the location of inline spam report that is inserted at the top of the message. Was this message transmitted using IPv6 or IPv4 in its last hop? To stop this header appearing, set it to be blank. The whitelist check is done before the blacklist check. If anyone whitelists a message, then all recipients get the message. If no-one has whitelisted it, then the blacklist is checked.
This setting over-rides the "Is Definitely Spam" setting. This value can be over-ridden by the "Is Definitely Not Spam" setting. Do you want to stop any virus-infected spam getting into the spam or MCP archives? If you have a system where users can release messages from the spam or MCP archives, then you probably want to stop them being able to release any infected messages, so set this to yes.
It is set to no by default as it causes a small hit in performance, and many people don't allow users to access the spam quarantine, so don't need it. This is a list of server names or parts of which are known to host web bugs. All images from these hosts will be replaced by the "Web Bug Replacement" defined below. Set where to find all the strings used so they can be translated into your local language. This can also be the filename of a ruleset so you can produce different languages for different messages.
Address of the local Postmaster, which is used as the "From" address in virus warnings sent to users. Where to put the virus scanning engine lock files. These lock files are used between MailScanner and the virus signature "autoupdate" scripts, to ensure that they aren't both working at the same time which could cause MailScanner to let a virus through. How to lock spool files. For sendmail, it defaults to "posix".
For sendmail 8. For Exim, it defaults to "posix". No other type is implemented. Log all occurrences of HTML tags found in messages, that can be blocked. This will help you build up your whitelist of message sources for which particular HTML tags should be allowed, such as mail from newsletters and daily cartoon strips.
Do you want to log all messages that are delivered and not delivered to the original recipients. Note that this log output will include the Subject: of the original email, so is switched off by default. In some countries, particularly the EU, it may well be illegal to log the Subject: of email messages. Do you want all non-spam to be logged?
Useful if you want to see all the SpamAssassin reports of mail that was marked as non-spam. Note: It will generate a lot of log traffic. Log all the filenames that are allowed by the Filename Rules, or just the filenames that are denied? Log all the filenames that are allowed by the Filetype Rules, or just the filetypes that are denied? Log all occurrences of "Silent Viruses" as defined above? Do you want all spam to be logged?
Useful if you want to gather spam statistics from your logs, but can increase the system load quite a bit if you get a lot of spam. Log all actions from the "SpamAssassin Rule Actions" setting? Do you want to log the processing speed for each section of the code for a batch? This can be very useful for diagnosing speed problems, particularly in spam checking. This is the version number of the MailScanner distribution that created this configuration file.
Please do not change this value. When a message is to not be virus-scanned which may happen depending upon the setting of "Virus Scanning", especially if it is a ruleset , do you want to add the header advising the users to get their email virus-scanned by you? Very good for advertising your MailScanning service and encouraging users to give you some more money and sign up to virus scanning. How many MailScanner processes do you want to run at a time? There is no point increasing this figure if your MailScanner server is happily keeping up with your mail traffic.
If you are running on a small system with limited RAM, you should note that each child takes just over 20MB. As a rough guide, try 5 children per CPU. But read the notes above. How much of the message should be passed to the Custom Spam Scanner. Most spam tools only need the first 20kbytes of the message to determine if it is spam or not. Passing more than is necessary only slows things down.
Max Custom Spam Scanner Timeouts. If the Custom Spam Scanner times out more times in a row than this, then it will be marked as "unavailable" until MailScanner next re- starts itself. The maximum depth to which zip archives, rar archives and Microsoft Office documents will be unpacked, to allow for checking filenames and filetypes within zip and rar archives and embedded within Office documents.
To disable this feature set this to 0. The maximum size, in bytes, of any attachment in a message. If this is set to zero, effectively no attachments are allowed. If this is set less than zero, then no size checking is done. This can also be the filename of a ruleset, so you can have different settings for different users.
You might want to set this quite small for large mailing lists so they don't get deluged by large attachments. Maximum Attachments Per Message. The maximum number of attachments allowed in a message before it is considered to be an error. Some email systems, if bouncing a message between 2 addresses repeatedly, add information about each bounce as an attachment, creating a message with thousands of attachments in just a few minutes.
This can slow down or even stop MailScanner as it uses all available memory to unpack these thousands of attachments. The maximum size, in bytes, of any message including the headers. If this is set to zero, then no size checking is done. You might want to set this quite small for dialup users so their email applications don't time out downloading huge messages.
Limit the number of attempts made at processing any particular message. If you get a message which repeatedly crashes MailScanner, it will limit the impact by ignoring the message and refusing to process it, after more than the given number of attempts have been made at it. Note that enabling this feature causes a slight performance hit. If more messages are found in the queue than this, then switch to an "accelerated" mode of processing messages.
This will cause it to stop scanning messages in strict date order, but in the order it finds them in the queue. If your queue is bigger than this size a lot of the time, then some messages could be greatly delayed. So treat this option as "in emergency only".
SpamAssassin is not very fast when scanning huge messages, so messages bigger than this value will be truncated to this length for SpamAssassin testing. The original message will not be affected by this. This value is a good compromise as very few spam messages are bigger than this. This will be the simple cut-off point for messages that are larger than this number. Once the size limit is reached, MailScanner reverses towards the start of the message, until it hits a line that is blank.
The message passed to SpamAssassin is truncated there. This stops any part-images being passed to SpamAssassin, and so avoids rules which trigger on this. Once the size limit is reached, MailScanner continues adding to the data passed to SpamAssassin, until at most the 2nd number of bytes have been added looking for a blank line. This tries to complete the image data that has been started when the 1st number of bytes has been reached, while imposing a limit on the amount that can be added to avoid attacks.
If all this confuses you, just leave it alone at "40k" as that is good. If SpamAssassin times out more times in a row than this, then it will be marked as "unavailable" until MailScanner next re-starts itself. This means that remote network failures causing SpamAssassin trouble will not mean your mail stops flowing. Spammers do not have the power to send out huge messages to everyone as it costs them too much more smaller messages makes more profit than less very large messages.
So if a message is bigger than a certain size, it is highly unlikely to be spam. Limiting this saves a lot of time checking huge messages. Disable this option by setting it to a huge value. This is measured in bytes. The maximum number of timeouts caused by any individual "Spam List" or "Spam Domain List" before it is marked as "unavailable". Once marked, the list will be ignored until the next automatic re-start see "Restart Every" for the longest time it will wait.
Max Unscanned Messages Per Scan. The minimum size, in bytes, of any attachment in a message. If this is set less than or equal to zero, then no size checking is done. It is very useful to set this to 1 as it removes any zero-length attachments which may be created by broken viruses. Minimum acceptable code stability status -- if we come across code that's not at least as stable as this, we barf.
This is currently only used to check that you don't end up using untested virus scanner support code without realising it. Levels used are: none - there may not even be any code. Don't assume it will work. It should work. Don't set it to anything other than "supported" on a system that could ever receive important mail. This sets the minimum number of "Spam Score Characters" which will appear if a message triggered the "Spam List" setting but received a very low SpamAssassin score.
This means that people who only filter on the "Spam Stars" will still be able to catch messages which receive a very low SpamAssassin score. Set this value to 0 to disable it. Allowed Values directory. If a location specified in "Archive Mail" is not found, should it assume that the location is a file or a directory name? Before this option was added, it was always assumed to be a directory.
This is only used by the "clamavmodule" virus scanner, not the "clamav" scanner setting. SophosSAVI only: monitor each of these files for changes in size to detect when a Sophos update has happened. The date of the Sophos Lib Dir is also monitored. This is only used by the "sophossavi" virus scanner, not the "sophos" scanner setting.
Set whether to use postfix, sendmail, exim or zmailer. If you are using postfix, then see the "SpamAssassin User State Dir" setting near the end of this file. Allowed Values add. What to do when you get several MailScanner headers in one message, from multiple MailScanner servers. Values are "append" : Append the new data to the existing header "add" : Add a new header "replace" : Replace the old data with the new data Default is "append" This can also be the filename of a ruleset.
Never Notify Senders Of Precedence. If you supply a space-separated list of message "precedence" settings, then senders of those messages will not be warned about anything you rejected. This is particularly suitable for mailing lists, so that any MailScanner responses do not get sent to the entire list. Strings listed here will be searched for in the output of the virus scanners.
It works to achieve the opposite effect of the "Silent Viruses" listed above. If a string here is found in the output of the virus scanners, then the message will be treated as if it were not infected with a "Silent Virus". A good example of this is a document macro virus or a Joke program.
Another word that can be put in this list is the special keyword Zip-Password : inserting this will cause senders to be warned about password-protected zip files, when they are not allowed. This will over-ride the All-Viruses setting in the list of "Silent Viruses" above.
The visible part of the email address used in the "From:" line of the notices. What signature to add to the bottom of the notices. Include the full headers of each message in the notices sent to the local system administrators? Do you want to notify the people who sent you messages containing viruses or badly-named filenames? The default value has been changed to "no" as most viruses now fake sender addresses and therefore should be on the "Silent Viruses" list.
Set location of outgoing mail queue. As an opposite to the "safe" list above, there is also a live continuously- updated list of known bad sites, which will always trigger the "Find Phishing Fraud" test described above.
This is a space-separated list of the names of files which contain a list of link destinations which should always trigger the test. This file should be updated hourly. If a potential phishing attack is found in the message, do you want to modify the subject line? There are some companies, such as banks, that insist on sending out email messages with links in them that are caught by the "Find Phishing Fraud" test described above.
