I thought about turning off pipelining on my real servers. The idea was to
delay the connection once (once as in a real server sending) to see if it
will actually deliver then never delay again

NOPE! Actually I don't want it, but it was one of those things that I
figured, the IPs are not publicised anywhere and thus any IP connecting to
it has abusive intent and I was going to build a blacklist based upon that.
I'm sure somewhere down the line hotmail,yahoo,aol,etc would get in there
some how but that's of no concern anyway (hotmail has never been able to
curb abuse from past experienced and they should be blacklisted)

RIght now, it's just to see what abusers are out there. Mostly korea and
china (big surprise, right?) and I've ip blocked the ones that don't give
up. Unfortunately the IPs are over a single 56k dialup and half are listed
as dynamic addresses by sorbs and other DULs (don't care I never intend to
use the IPs for legit purposes)

Found tons of HTTP abusers so I turned off the service. Oddly enough I
haven't found many SSH abusers. One IP must have been an open proxy and
I've seen tons of relay attempts via HTTP, but this is OT here anyway.
