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.
