Tagged Message Delivery Agent (TMDA) Copyright (C) 2001,2002,2003 Jason R. Mastaler <jason@mastaler.com>
This software is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative.
TMDA is an open source software application designed to significantly reduce the amount of spam (Internet junk-mail) you receive. TMDA strives to be more effective, yet less time-consuming than traditional spam filters. TMDA can also be used as a general purpose local mail delivery agent to filter, sort, deliver and dispose of incoming mail. The technical countermeasures used by TMDA to thwart spam include:
* whitelists: accept mail from known, trusted senders.
* blacklists: refuse mail from undesired senders.
* challenge/response: allows unknown senders which aren't on the whitelist or blacklist the chance to confirm that their message is legitimate (non-spam).
* tagged addresses: special-purpose e-mail addresses such as time-dependent addresses, or addresses which only accept certain kinds of communication. These increase the transparency of TMDA for unknown senders by allowing them to safely circumvent the challenge/response system.

This is the WLE (White List Email) program, designed to keep unsollicited mails far from your mailbox.
This is a prerelease: the program works for me, but it is not guaranteed to work for anyone else. Moreover, there is no express setup nor any configuration guide.
Have a look at the INSTALL and sample-* files for basic instructions.
