Quoting Trent W. Buck (trentbuck@gmail.com):
I think I already mentioned null-mx and tarpit anti-spam techniques upthread, but I'll say it again:
example.org IN MX 10 null-mx.example.org example.org IN MX 20 mail.example.org example.org IN MX 30 tarbaby.junkemailfilter.com
Sold. And thanks for the reminders. I've long considered the null-mx trick, as the logic is compelling, and just implemented now. The tarbaby thing I'm a very tiny bit leery about for the same reason you are, but am giving it a try.
