You are assuming that every user will opt to turn TMDA "on", which
won't be the case.  Also, Cory's point is a good one.  TMDA should
kick in only after the most obvious spam is shut down at the SMTP
level.

Even if it means your users might lose mail because of it?  See my
previous message, and make sure you've thought through the
ramifications of doing this.

I picked up an 80GB disk at Sam's Club last week for like $100USD.  I
would think a small expenditure like this would be worth the
additional benefits for your customers.

In practice, this isn't the case, which is why this hasn't been
requested before.  And yes, there other large systems using TMDA.

FWIW, this patch won't be something I'll be adding to the
distribution.  First, there isn't enough general interest for it, and
second I disagree with it philosophically.  

You'd be better off using a challenge/response system that operates at
the SMTP level.  It's a waste to have something like TMDA accept and
process the message if you're not even going to store it.
