I've installed Spam Assassin on you server and Anomy Sanitizer. Both of these are email filters. The first, Spam Assassin will attempt to falg all emails that pass through our server sa spam. The second will remove all attachments from our emails that appear to be viruses.

Spam Assassin is a passive filter. What it does is add email headers to each email that passes through. The headers will be in the form of

X-Spam-Status: No, score=0.0 required=5.0 tests=none autolearn=ham

or

X-Spam-Status: Yes, score=17.0 required=5.0 tests=none autolearn=ham

What this allows you to do is add rules to your mail client, MSN, Outlook, Netscape, etc., to filter based on these headers. An example is to add a rule to Outlook that says "If the message has a header called "X-Spam-Status" and a value that starts with "Yes" then place it in a folder called SPAM. The benifet to this approach over just having spamassassin delete the message is that you can review the spam and make sure it is spam if yu so desire. Also, if yu don't want to do the filtering then you can not add this rule to your mail client and all is normal

The second mail filter, anonmy, does alter emails. It removes all things it thinks are viruses and all things that can contain viruses, like executables. If it finds something "dangerous" then it replaces the attachment with a text file that says

***** NOTE: An attachment named gpgsplit.exe was deleted from this message because it contained a windows executableor other potentially dangerous file type. Contact the system administrator for more information.
