Coherent Mail Gateway is intended to be a very easy to set up MTA using SMTP and POP3. Greylisting is used on the SMTP daemon to reduce spam.
In addition, quite a lot of checks on the validity of information from the SMTP client (such as claimed server name and sender) are carried out, and anyone caught telling lies is disconnected.
Grey-, black-, and white-listing are supported, as well as (optionally) ClamAV and Spamhaus. The target market is users with static IP addresses. Others can use the system, but its value will be limited to outgoing email.
· Perl 5.8.0
What's New in This Release:
· The SMTP server now dynamically bans persistently abusive IPs for a period.
· Performance is enhanced, and users may be given passwords to relay through the SMTP server from remote locations.
