Projects / MailScanner


MailScanner is an email virus scanner, vulnerability protector, and spam tagger. It supports the Postfix, Sendmail, Exim, Qmail, and ZMailer MTAs, and the Sophos, McAfee, F-Prot, F-Secure, CommandAV, InoculateIT, Inoculan, eTrust, Kaspersky, Nod32, AntiVir, BitDefender, RAV, Panda, DrWeb, ClamAV, and other anti-virus scanners. It uses SpamAssassin for highly successful spam identification, and is designed to handle denial of service attacks. It will detect password-protected zip files and apply filename checking to their contents. It is very easy to install, requires no changes at all to your file, is designed to be lightweight, and won't grind your mail system to a halt with its load. It can be integrated into any email system, regardless of the software in use.

Recent releases

    Release Notes: Fedora 10 is supported. tnef was upgraded to 1.4.5. A patch was added to ClamAV and SpamAssassin to make the Mail::ClamAV Perl module handle ClamAV 0.94 correctly. mcafee-autoupdate was fixed so that it will work properly.

    •  07 Jun 2006 12:16

      Release Notes: There is now an alternative phishing net which is less strict than the original. It knows all about top-level and second-level domain names in countries around the world, and will allow a link that points to the same company as the text it claims to be. This is particularly useful for ISPs who cannot use the phishing net because it caused too many false alarms. Support for Sophos 5 has been added. Contents of gzip-ed archives will now be checked for filenames and filetypes. Detection and removal of Web bugs was improved.

      •  01 Mar 2006 13:49

        Release Notes: A "Use TNEF Contents" feature was added, which you can use to add to a message the attachments which are held in the "winmail.dat" file in an "Outlook Rich Text Format" message.

        •  01 Feb 2006 09:21

          Release Notes: There are great speed improvements, often as much as a 40% speed improvement. Virus scanners are automatically detected. No configuration is required on sendmail systems. A UU-decoder was added to allow filename and filetype traps in UU-encoded files inside attachments. Many command-line options were added to the "MailScanner" command so you can test your configuration, evaluate rulesets, and debug your installation without have to set the debug options in MailScanner.conf.

          •  01 Jan 2006 16:06

            Release Notes: This version is noticeably faster than before. File name and file type restriction rules are also greatly simplified, so everyone can actually understand it.

            great software
            I installed Mailscanner along with clamav on a Pentium II - 64 MB ram linux box and its doing great job for my company, about 60 users, scanning both inbound and outbound mail traffic for Lotus Notes.

            The built-in SPAM checking based on online RBL lists was so efficient that i didnt need SpamAssasin at all.

            Top Shelf!!
            This is an outstanding package. Running on Redhat ES 3.0 no problem.Can be installed in under 5 mins out-of-the-box. Just install a virus program, make a small change in the MailScanner.conf file and your done!Take a look on the pricing on an enterprise class scanner (Very expensive).

            Great job.. Top shelf

            Re: Sex on toast - Keep it up
            I've tested before Amavis, but now I am
            delighted about MailScanner. I simply recommend
            it! I am using Slackware 9.1.0, Postfix-2.0.18
            and after I've turned on MailScanner+ClamAV
            +SpamAssassin, most of the problems went off.

            Great job, congratulations to the author!
