:) I was using pcretest. Yes, I figured out it would never match what
I expected.

What I sort of settled on so far:

/213\.37\.(?:1[5-9][0-9]|2(?:[1-4][0-9]|5[0-1]))\.\d{1,3}/

Not sure what Tony will do. The RegEx originally posted was long but
worked correctly and consistently -- the question as posted was did
anyone know of a site that had done this work for most spam sites
already. I was just trying to see if there was any way to shorten the
amount of work needed for "like" RegEx's in the future.

If I look at the "million monkeys" rule I believe all sites will
eventually be blocked by all MTAs and e-mail spam will be solved once
and for all :)
