Seriously Paul, I would like to have some kind of announcement made on Nanog before you do that again, so that people can tell you not to do it. Breaking a large service provider is definitely an operational issue. How
I'm suprised that people haven't done a better job at building better SMTP filters.. Unfortunately what I wrote was on company time, so I can't release it (grrrrrr), but I definately have the flexability to do stuff like this (indeed, this isn't the first time MSN mail was blocked, and I was not affected by Vixie's decisions): + :rbl:true * * 550 You are on Vixie's list, see ... [macros to generate http address] or contact postmaster () calweb com to override the RBL. + any:msn.com any:msn.com * 250 Permit MSN's machines to send MSN-originated email I'm not sure how easy/hard it would be to maintain *sendmail* that way.. However, as a seperate process, there isn't that much overhead on what I'm currently running to make intelligent decisions following a list of rules, that do things like override MSN-originated email (we still refuse 151251 () 34581235 com from MSN boxes), to require juno.com email actually come from juno.com email servers, and other silly tricks. I get 1-2 emails a week for individuals that get caught by the frontend that are legimate, which get immediately put into the rulesets. Anyone who can read the bounce message, is by definition from a valid email address..
