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.
