scripts default iconMailScanner for Email System Utilities Publisher's description

MailScanner is an email virus scanner and spam removal tool.

E-mail viruses costs businesses millions of pounds every year. Spam accounts for around 60% of all e-mail traffic, wasting large quantities of network bandwidth and resources.

There are many commercial e-mail systems available for a high cost that claim to help stop spam, but they are rarely effective in real-world environments. They provide support for a very restricted set of virus scanners, usually one or two, forcing the use of particular products in what should be a separate purchasing decision.

MailScanner is a highly-respected open source e-mail security system, with more users than AOL and Hotmail combined. It is used at over 30,000 sites and processes over 500 million messages per day. It supports the use of any combination of 20 different commercial anti-virus engines for reliability and good coverage. Its anti-spam system incorporates SpamAssassin, which without doubt is the best anti-spam engine available at any price. MailScanner has been in continuous development for nearly 4 years. In that time it has grown from a simple virus scanner implemented in 1200 lines to a complete email security and anti-spam system of over 30,000 lines, and has been re-designed and rebuilt from the ground up as necessary to ensure the architecture is suitable for the complexity of the system.

MailScanner has been deployed in over 60 countries around the world, and is used for scanning mail destined for all 7 continents (even Antarctica). It scan over 5 billion messages per week for numerous large government departments, corporations, non-profit organisations and educational institutions. It is currently used by some large ISPs and mobile telephone companies in the UK and Europe, along with the largest space agency. It is now downloaded over 20,000 times each month, with a total of over 1/4 million downloads.

MailScanner is an open-source package, though the development model is slightly different to that used by many other projects. The author keeps tight control over the state of the source code, and other people are not allowed direct access to the latest development code that is stored in the CVS source repository. The major reason for this is that email is a business-critical application and considerable damage could be caused (such as the loss of email messages) if a "trigger-happy" administrator installed untested code that was in the middle of a critical development stage.

Tested and proven releases of the code are frequent, so that the users can get access to the latest features as they are written. But untested code is not allowed out into the public domain. This approach has definitely helped build MailScanner's reputation as a highly reliable system, something that is not necessarily possible if administrators are allowed to install untested code.
