Please mind the fence.
Spamgate is a custom built, highly scalable anti-spam and anti-virus server built by 3DPixel Ltd.
Spamgate is built upon the highly successful Qmail mailserver supplemented by John Simpson's Qmail Patches, the Spamassassin project and ClamAV.
At the moment, Spamgate integrates with any version of the Parallels Plesk Control Panel.
Spamgate is designed to be installed on a seperate server thus providing an independant spam filtering mail relay. It does not alter Plesk in any way. Redundancy can simply be achieved by adding mirrored servers with Spamgate installations.
We will be releasing the implementation of Spamgate in the near future.
