Fighting malware and spam with Postfix

This paper demonstrates how to use the filtering capabilities of Postfix to perform high-level content filtering including:

* Dropping potentially hostile attachments such as .EXE and .VBS files
* Preventing MS Outlook from auto-executing unknown attachments
* Preventing MIME and HTML exploits
* Disabling "web bugs" that spammers use to track recipients
* Identifying spam based on message content

Anti-Spam How To

This is intended as a step-by-step guide to setting up an anti-spam e-mail gateway utilizing some of the most effective tools available. While these instructions may be adapted to other configurations, they are written for a Debian Linux installation.

Amvisd-New

amavisd-new is a high-performance and reliable interface between mailer (MTA) and one or more content checkers: virus scanners, and/or Mail::SpamAssassin Perl module. It is written in Perl, ensuring high reliability, portability and maintainability. It talks to MTA via (E)SMTP or LMTP protocols, or by using helper programs. No timing gaps exist in the design, which could cause a mail loss.
