The problem I have with such systems is that if they become popular,
spammers will simply setup anti-TMDAs.  Since the TDMA simply requires a
reply to the given address to send the mail, a spammer need only use a
valid From: and then setup their own robot to reply to incoming mail (as
long as it looks like spam they sent out, of course).

I agree that while TMDA systems are in the minority, they are useful,
but if lots of ISPs pick them up, spammers will just get smarter.

The same thing has happened with "spam protected" email addresses on the
web.  Most spam webbots are now smart enough to try removing "NOSPAM" or
a few of the more common anti-spam parts from email addresses.
