We have been seeing a dramatic increase of free webmail server IP's being blacklisted and causing false positives from the usual Hotmail, msn, yahoo, aol, gmail, and other free email servers listed on RBL', spamcop, spamhaus, etc.
This has caused a tendency to for customers to want to whitelist these domains which we do have on per domain/per user settings however still must be explained and applied. I can provide hundreds of these blacklisted IP's in the logs however I was hoping a number of you have developed a list of reverse DNS IP or hostname entry files to subtract from sniffer and/or UR-IBL scoring that will allow the good emails through from blacklisted IPs or some ruleset that has the same effect. This has become a very annoying issue for us, any help/ideas would be appreciated.
