To be fair, they do recommend that users don't block at level 3.

I still think their listing criteria are dumb. The seem to use three
techniques:

1. People who bounce viruses with warning messages (actually, that's fine).

2. People who use SRS. I'd like to use it for local people that ask to get
email forwarded from their local (sussex.ac.uk) address to a personal
address. I don't see how SRS can harm anyone when I do this. Perhaps such
email would never hit their honeypots, though.

3. People using sender verification callouts. They seem to think it's as
bad as sending email, but my sender verification callouts don't fill
mailboxes or server queues. And, they do stop lots of spam.
