Seamless Integration Into Any Existing E-Mail Environment

CleanMail was designed to make the integration into existing e-mail environments simple and straight-forward.

Fingerprint Filter

CleanMail's Fingerprint filter calculates message fingerprints (fuzzy hashes) and compares them against a database of known spam message fingerprints. If a message fingerprint matches a known spam message fingerprint, the mail is blocked. If a message is blocked by another filter, its fingerprints are automatically added to the database, speeding up the processing of similar spam messages.

Delay Filter

CleanMail Server can be configured to use a built-in delay filter to stop spammers from delivering junk mails to your server. Tests have shown that the Delay Filter itself already blocks up to 73% of all junk mails while causing only minimal resource usage on the host system. The effect of delay filtering is comparable to greylisting, but delay filtering of course avoids the common drawbacks of greylisting.
