MailScanner is a complete e-mail security system designed for use on
|
||
|
e-mail gateways. It protects against viruses, and detects attacks against
|
||
|
e-mail client packages (such as Outlook, Outlook Express, Eudora). It
|
||
|
can also detect almost all unsolicited commercial e-mail (spam) passing
|
||
|
through it and respond to all incidents in a wide variety of ways.
|
||
|
|
||
|
Not only can it scan for known viruses, but it can also protect against
|
||
|
unknown viruses hidden inside e-mail attachments by refusing entry to
|
||
|
attachments whose filenames match any given pattern. This can include
|
||
|
generic patterns that trap filenames attempting to hide the true filename
|
||
|
extension (e.g. ".txt.vbs").
|
||
|
|
||
|
It is superior to many commercial packages in its ability to handle
|
||
|
attacks against itself, such as Denial Of Service attacks caused by
|
||
|
messages containing the "Zip of Death". It is easy to install into an
|
||
|
existing e-mail gateway, requiring very little knowledge of sendmail
|
||
|
and no change to an existing sendmail configuration.
|
||
|
|
||
|
MailScanner itself is entirely open source, but it uses widely known
|
||
|
commercial virus scanning packages at its core. The other software it
|
||
|
uses is all high quality open source software, leading to a system that
|
||
|
can be trusted for performance and reliability.
