Qmail-Scanner

Qmail-Scanner, (also known as scan4virus) is an addon that enables a Qmail Email server to scan all gatewayed Email for certain characteristics. It is typically used for its anti-virus protection functions, in which case it is used in conjunction with commercial virus scanners. but also enables a site to react to Email (at a server/site level) that contains specific strings in particular headers, or particular attachment filenames or types (e.g. *.VBS attachments). It also can be used as an archiving tool for auditing or backup purposes. Qmail-Scanner is integrated into the mail server at a lower level than some other Unix-based virus scanners, resulting in better performance. It is capable of scanning not only locally sent/received Email, but also Email that crosses the server in a relay capacity. It also has SpamAssassin support.

Recent releases

  •  06 Oct 2011 06:36

    Release Notes: Some minor bugs were fixed. New features include DLP support and Team Cymru Malware Hash Registry support.

    •  04 Apr 2006 05:06

      Release Notes: Many changes were made, including the ability to quarantine high-scoring spam along with viruses and policy blocks, a new format for the quarantine-events.txt policy file, and normalization of strings to make pattern matching more consistent.

      •  16 Mar 2004 10:12

        Release Notes: In this version, zip files are no longer deleted after unpacking to allow AV a better go at the original zip. It now has the option of blocking password-protected zip files ("--block- password-protected"). As almost all viruses forge the mail envelope, it now defaults to not alerting anyone. However, if the "block" occurred due to a policy reason (instead of an AV), then they are still notified.

          Release Notes: This release now runs under its own account. This gives better security and is much easier to audit. This version also features better accounting records, as well as more pro-active content-filtering, in an attempt to stop novel viruses/trojans.

          •  13 Feb 2003 11:09

            Release Notes: This version fixes some issues with SpamAssassin tagging, adds support for the RAV scanner, and alters some error messages.

            qmail-scanner patches, tricks & enhancements

            Current version of qmail-scanner (http://qmail-scanner.sourceforge.net/)
            (0.96) hangs when it found an encrypted .zip (the mail will never queued):
            there's also a problem when an older uudecode command (found on many
            Debian (http://www.debian.org/) distributions) is encountred during
            the installation.

            I also added some tips for installing qmail-scanner in a vpopmail enviroment
            and published a very complete list of "dangerous" extensions
            for Mircosuk operating systems.

            If you are interested, check my home page (http://exe2bin.com/),
            or go directly to the qmail-scanner
            directory.
