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 unk kinds of communication. These increase the transparency of TMDA for unknown senders by allowing them to safely circumvent the challenge/response system.
This combination was chosen based on the following assumptions about the current state of spam on the Internet: - You cannot keep your email address secret from spammers.
- Content-based filters can't distinguish spam from legitimate mail with sufficient accuracy.
- To maintain economies of scale, bulk-mailing is generally:
- An impersonal process where the recipient is not distinguished.
- A one-way communication channel (from spammer to victim).
- Spam will not cea;/li>
