Python-based SPAM reduction system
Tagged Message Delivery Agent TMDA is designed to significantly reduce the amount of spam junk-mail you receive. TMDA strives to be more effective, yet less time-consuming than traditional spam filters.
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.
TMDA can also be used as a general purpose local mail delivery agent to filter, sort, deliver and dispose of incoming mail.
