The world's most widely-used e-mail security and anti-spam system
MailScanner was created and developed by Julian Field and launched in 2000. It is now a highly respected open source e-mail security system, protecting over 40.000 sites around the world, including top government departments, commercial corporations and educational institutions. The technology is fast becoming the standard e-mail solution at many ISP sites for virus protection and spam filtering.
Anti-Virus
MailScanner can use several virus scanners concurrently and therefore guarantee maximum anti-virus protection. Currently supported virus scanners include Sophos, McAfee, BitDefender, Dr. Web, Kaspersky, eTrust Antivirus, Nod32, F-Secure, F-Prot, Panda, RAV, AntiVir, ClamAV, TrendMicro, Norman, AVG and Vexira.
Our experience of the past decade clearly proves that anti-virus software reacts differently on each new virus threat. Unfortunatly no single anti-virus software vendor is always the fastest to provide new virus signatures. Therefore we recommend the use of several anti-virus software products and have MailScanner scan each e-mail with several scan engines before delivering the e-mail to your local mailserver.
MailScanners sophisticated e-mail handling allows for intelligent scanning of all e-mail contents. Simple renaming of files or putting files into archives cannot fool MailScanner. Once you defined what file types are on the blacklist, MailScanner will filter these files in every possible way. Moreover MailScanner also includes advanced anti-phishing mechanisms to protect your users.
Anti-Spam
Unsolicited e-mail is more and more getting the single most problem for modern communication systems. Fighting SPAM therefore is a big challenge. MailScanner is deeply integrated with SpamAssassin, one of the most effective anti-spam frameworks currently available.

Seceidos and MailScanner
Seceidos has been using MailScanner since its foundation in 2002. Soon we discovered the extraordinary potential of this wounderful piece of open source software. Soon after we started developing and maintaining the official FreeBSD port of MailScanner.
The FreeBSD MailScanner port allows easy installation of the MailScanner scanning framework on all FreeBSD systems (4.X, 5.X and 6.X). All dependencies are installed and maintained automatically.
