Xmail Server is an excellent free open source SMTP/POP3/FINGER Mail Server by Davide Libenzi.

On this page you will find a some scripts or tools I have written quick'n'dirty for use with Xmail Server. They are used in real-world environment and are considered very useful for a long period. This may not necessarily be the case for everyone else than me, but they may at least be a starting point for you and leave room for your own modifications.

only two aliases 'samplelist-subscribe' and 'samplelist-unsubscribe' are needed per mailing list
