Mail::SpamAssassin::Plugin::LDAPfilter

Mail::SpamAssassin::Plugin::LDAPfilter provides LDAP-based blacklist and whitelist filtering capabilities to SpamAssassin 3.x installs. Standard elements from the SMTP session and the RFC822 message are parsed out and searches are submitted to an LDAP server, and scorable responses are returend for any matches. For example, if a message contains a parseable domain name, the domain name will be used as a search key against the LDAP filters, and if a match is found the plugin will return a scorable marker, which could either be positive (blacklist) or negative (whitelist).

SAGrey

SAGrey is a two-phased greylist tool for use inside spamassassin. It first looks to see if the score of the current message exceeds the current "spam" threshold value, and if so then it looks to see if the message sender's email and IP address tuple are already known to the auto-whitelist (AWL) repository. If the message exceeds the spam score and the sender is unknown to spamassassin, SAGrey assumes that this is one-time spam from a throwaway or zombie account, and fires accordingly.

This is badly named, as it does not actually do greylisting.
