Over 10,000 companies trust Xeams to be their primary email filtering system. You must try Xeams before investing thousands of dollars on any other message filtering and archiving solution.


100% In-house Xeams is 100% in-house solution. We can't trust our emails going through any other company on the Internet and you should not either.
3 Modes Xeams can run in 3 different modes:

  • Stand-alone - with no other server
  • Firewall - run it as a spam-firewall in front of your actual email server, such as MS Exchange, IBM Dominos, Zimbra or any other.
  • Hybrid - a combination of the two modes above.
Junk filtering Xeams provides 99% spam filtering right out of the box. Sophisticated score-based filtering rules are applied to every inbound and outbound message. The messages are filtered before they hit your actual email server.
End-to-End Encryption Besides using SSL/TLS to encrypt messages during communication, Xeams offer end-to-end encryption for users who need to send sensitive information to their clients or business partners. Click here to watch a video on this topic.

Clustering Run multiple instances of Xeams in a Master/Slave configuration allowing easy administration. Changes made to rules on one master server can automatically propagate to the slave without any human interaction.
