Features > Anti-Spam > SpamAssassin SpamAssassinSpamAssassin is an open-source mail filter project designed to identify spam. It uses a diverse range of tests and has been shown to be very effective in separating spam from non-spam mail.
Because SpamAssassin integrates multiple techniques and is being continuously updated and extended it has an advantage over other anti-spam systems.
Although SpamAssassin also uses Bayesian statistical techniques to analyse mail, it also tests for many features that are very hard for spam senders to avoid. The spammer's objective is to spread advertising (or some message) as widely as possible, with as little cost to themselves as possible. In order to accomplish this the spammer must employ many methods that are not typical of regularly sent mail. For example, spammers may attempt to obscure the actual message using images or unnecessary HTML markup and SpamAssassin will factor this in when assessing a message.
See the SpamAssassin-tab for information on configuring the SpamAssassin integration.

 Working with SpamAssassin for Win32
Download the SpamAssassin files to get started.
SpamAssassin 3.2
Download SpamAssassin for Win32 here
New User
If you are a new user all you need do is:
Shutdown Mailtraq
Unzip the SpamAssassin download (multiple files) into Path:\Program Files\Mailtraq
Restart Mailtraq
And set the configuration as illustrated right.
Existing Users
If you are an existing user who previously used this download: SpamAssassinForMailtraq.msi
and configured it as illustrated, then all you need do is:
Shutdown Mailtraq
Unzip the SpamAssassin download (multiple files) into Path:\Program Files\Mailtraq
Restart Mailtraq
If you wish to install SpamAssassin elsewhere, then enter the server address or path to spamd.exe as indicated in the dialog box.
Configuration
We suggest you create a User in Mailtraq called spam and provide webmail access to that mailbox, and then configure the Anti-spam as illustrated above. It is then a simple matter for any user with webmail access to the spam mailbox to check for false-positives. You should set the Archive properties of the spam mailbox to delete messages after a period of time.
SpamAssassin can be run in conjunction with Mailtraq's Bayesian analyzer (as illustrated) or can be used to replace Mailtraq's analyzer by selecting the bottom radio-button in the dialog.
You will get the best results if you run SpamAssassin in conjunction with Mailtraq's Bayesian analyzer.

Mailtraq supports the latest version of SpamAssassin and now that it is being regularly produced as a Win32 binary there is no longer any need for us to provide our own custom build. You simply install it and tell Mailtraq the path to the spamd.exe file, and it does the rest. The advantage is that administrators can update as often as they wish and have complete control over customization.
Mailtraq News October 2007
Mailtraq introduced support for SpamAssassin for Win32 in 2.11.0.2234
Configuration Tips
1.) The SpamAssassin engine takes several minutes to start after restarting Mailtraq. You may see Mailtraq Event Log entries similar to the following:
[Time] SpamAssassin: "" from (error=Windows socket error: No connection could be made because the target machine actively refused it (10061), on API 'connect')
This simply means that the SA engine was not yet ready to accept connection. No action is required.
2.) SpamAssassin will require at least 1GB of RAM to operate smoothly.
