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.
