MXtreme thus specifically resists operating system attacks, protecting your mail servers from direct SMTP and HTTP connections and effectively firewalling not just these traffic types, but all other attacks which may exploit them. MXtreme's MTA includes relay protection and has sophisticated mail routing to meet the needs of the largest organizations.

MXtreme avoids the problems and challenges of installing, configuring, hardening and maintaining a general purpose operating system.

MXtreme is also the only Common Criteria EAL4+ certified email firewall to provide military-grade security while dramatically improving the throughput of your mission-critical email infrastructure.
