It would be a great help if mozilla mail supported TMDA. TMDA cuts down on spam by making non-whitelisted senders respond to a challenge, which spammers wouldn't/couldn't (fake from: address) do. TMDA seems like it's a very effective anti-spam system, and I'd like to see support for it.

*** Bug 215875 has been marked as a duplicate of this bug. ***
My bug was just marked as a dupe (that's OK of course). But I searched for such a bug before opening a new. However I didn't find this one, because I did not search for "TMDA", but for "spam"/"junk"/"automatic reply"/"confirmation email". Is it possible to some of those to the Summary so people can find this bug easier? Maybe: "TMDA support missing (send automatic reply and wait for confirmation, when email is possible junk)" Furthermore I think the Bugzilla-Team shuld introduce a new Component of Mail/News "Junk Defense/Filtering" as this is becomming a more important part of Mail/News in the future, which isn't really Backend.
I'm not sure implementing TMDA on the client side is really a good idea. After all, spam would still have to be downloaded and kept on the hard disk, so when the sender is verified, the mail could be passed on to the user. Scott, any ideas on this? Or resolve as WONTFIX?
Summary: TMDA support missing → TMDA support missing (automatic reply, wait for confirmation by unknown senders; challenge/response)
See http://www.spamcop.net/fom-serve/cache/329.html about why autoreply is bad, challenge/respose is worse (they both contribute to the spam PROBLEM, not its SOLUTION), and how to replace them by better methods.
