Philter is a mail sorter for Qmail style Maildirs. It is written in Python and a properties file is used to setup the philters for filtering the mail :-)

Philter is copylefted under a GPL license. Philter only works on linux. No windoze ! It is meant to be used in tandem with a mail retriever like getmail. I use the mailwatch plugin for gkrellm to get my mail with the following command:
        getmail && philter.py.

The latest version: philter-1.1.tar.gz
