    Release Notes: This release added default poisoning of the application/x-msdownload MIME type in response to a new worm. Full MIME-type poisoning support will be available shortly. This release was accelerated for security reasons.

      Release Notes: The unrar executable check was fixed to not test for unrar if RAR scanning is already explicitly disabled by $DISABLE_RAR_SCAN. Recipient notification now works when sanitizing on a relay (e.g. in front of an Exchange server).

              Release Notes: A bug in null-boundary sanitizing was fixed. A hanging bug in decoding some Office/ZIP attachments to attached messages was fixed. A bug in scanning non-base64-encoded document/zip attachments was fixed. ZIPs are now detected by MIME type, not just by filename. Updating to this release is strongly recommended.

                Release Notes: Unusual formatting of base64 attachments intended to bypass filters is now detected. More HTML tags that can be used to attack mail clients or deliver web bugs are now defanged. Other minor bugfixes and enhancements were made.

                  Release Notes: This release fixes a small bug in the zip scanner that caused it to be too paranoid in checking zipped filenames, resulting in false-positive quarantine of some messages.

                    Release Notes: This version adds the ability to scan ZIP archive attachments for suspicious filenames, and quarantine messages that match. It adds the ability to use CPAN modules for some tasks instead of external programs. There were minor bugfixes and other enhancements.

                      Release Notes: The Smart Sender Notification Suppression was made a bit smarter. See SECURITY_TRUSTED_MTAS in the Configuration documentation for more details. The DISCARD and NOTIFY tie-in was fixed, so it can now DISCARD without notifying. .tmp files are now cleaned up on mimencode failure. Updating to this version is highly recommended, as it will not respond to forged NovArg/MyDoom attack messages.
