Anti-Spam SMTP Proxy "Anti-Spam SMTP Proxy" is a spam filter that sits on port 25 (smtp), and optionally also 465 (smtps) and 587 (submission), in front of your regular SMTP server.

ASSP relays the SMTP dialog between an incoming client and your SMTP server, intercepting the dialog as needed. ASSP performs a number of configurable spam checks and on detectinga spam message provides an immediate 5xx SMTP error code back to the client.

Non-spam messages are passed to the regular SMTP server for further processing and delivery. Spam messages can be blocked from delivery or subject-tagged and delivered.

ASSP offers: a whitelist of known good senders Bayesian checks on message headers and contents local user validation using RFC822 checks flat lists or LDAP lookup relay denial, HELO checking, SPF (Sender Policy Framework) checking, DNSBL (DNS Block List) checking using many block list services delaying of messages from unknown senders Virus detection.

assp fails to start with an error "setting up modules....Can't call method "VERSION" on an undefined value at sub main::init line 312." if the ClamAVd is not available.
the 'DoRFC822' failed, if the host name of a envelope sender address was valid but the domain nearest to the TLD was invalid, like in 'co.delaware.pa.us' where 'delaware.pa.us' is invalid
improved performance for high workload systems
better garbage detection for the HMM and Bayesian engine
