The project aims to develop useful filters that are built on the courier-pythonfilter framework by Gordon Messmer (http://phantom.dragonsdawn.net/~gordon/courier-patches/courier-pythonfilter/) for Courier MTA.

The filters are meant to be used on a mail system that has LDAP as its alias, authentication and authorization database.

Current list of available filter modules

• SigAppender - appends signatures to plain and HTML mail messages based on LDAP attributes and predefined template files
• FromNormalizer - normalizes sender data in the From: header based on LDAP attributed for the given account
