[Mimedefang] Netblock 222

[Curtis]

Mark,

We block 220 and 221 as well. We do this with the
access control in Sendmail though. We have never had
legit email from those networks. We are also thinking
about doing this to a CIDR block starting from 208 and
going all the way through 223. I do not think we would
miss much legit email, if any.
