With the Warden Antispam and Virus protection, you get the best of both worlds. Open source standards for content filtering from Amavis®, SpamAssassin®, and ClamAV® combined with deep integration with the Plesk control panel.
With support for over 25 SpamAssassin plugins, inbound/outbound scanning, database logging, custom rule builder, spam and virus quarantine, real-time spam learning, rich reporting, and multi-role access, Warden provides you with the most robust, extendable anti-spam and anti-virus solution for Postfix anywhere.
Product Information
Amavis Content Filter
Amavis is a high-performance interface between Postfix, SpamAssassin, and ClamAV. Amavis has been the gold standard used by large email providers for over a decade.
