Something I've seen before is a lot of mail servers will wait 10-45 seconds
before presenting an SMTP prompt to remote hosts; spambots typically won't
wait that long and give up. But since Verizon's sender verification (as of a
couple months ago; haven't checked recently) times out after 30 seconds,
that technique can have the side effect of making Verizon customers
unreachable.
