MailScanner scans all e-mail for viruses, spam and attacks against security vulnerabilities. It is not tied to any particular virus scanner, but can be used with any combination of 14 different virus scanners, allowing sites to choose the "best of breed" virus scanner. Being open source, site administrators can audit and verify the integrity of the system. Its role is a major part in the security of a network, and so it must act as a trusted service. The only way to achieve the required level of trust is to be open source, an approach the commercial suppliers are not willing to take. MailScanner has been developed in a world-leading Electronics and Computer Science Department at the University of Southampton, and is distributed for *FREE* under the GNU Public Licence.

With this software comes ClamAV a great, open source Virus Scanner.
