The ipt.* blocking dates back many years, I think the intercepter stuff 
does too.

The recommendation from AOL to rDNS block ipt.* dates back several 
years, and is mentioned in the current postmaster's guide at AOL.

Over the past several months I noticed we were getting a lot of ipt.* 
hits, and Hutzler later said that some of their blocks in (IIRC) Europe 
were apparently not working.  Obviously, they just fixed it.

We get virtually nothing but spam from rly.* too, so, we're blocking it 
now.  Hutzler remarked "you won't miss much", but I wouldn't take that 
as an official pronouncement. We get a handful of FPs on it per month, 
and we tell them to use the proper smarthosting.
