Sean Donelan [1/17/2004 9:20 AM] :True, but it appears AOL has cranked something up in the last couple of weeks or something is choking more often. If you look at various places where users like to gripe, you'll notice an uptick of queries and complaints on the subject.
Maybe they finally rolled this out across the board? AOL has a lot of dialup IP space (two /10s I think).
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.
