I have a static IP address and run a smtp server. My isp puts all the
static ip addresses into the dns blackhole lists. I use my ISP's mail
server as a smart host and send mail through it. If a user such as
myself misconfigures their smtp server to act as an open relay then
(hopefully) a receiving mail server will check the dns blackhole lists
and refuse to accept the email.

Thus users misconfiguring their own email servers should no longer be
used as a source of spam.

Unfortunately this seems a common business tactic, but perhaps it is
thought that business customers are less likely to misconfigure smtp
