Mailismus

Mailismus is a high-speed, high-volume mailserver, which can be used as an outgoing SMTP server, an MX secondary, or as a distribution point for incoming mail. It is secure, highly configurable, provides numerous anti-spam measures (for example blacklisting and greylisting, DNS-based address validation) and offers extensive logging, auditing and transcript options.
