I have a 2003 exchange server that was attacked by a email trojan that I removed last week. We were blacklisted with several services so I changed the Public IP of the server and that cleared us off of the mxtoolbox blacklist. We are still being blocked by att.net and aol. Trying to get us off their lists seems to be impossible. With att.net I filled out their delisting form and sent it and it twice a couple of days ago and have not heard a thing and we are still being blocked. Trying to speak to anyone at AOL seems to be impossible. Any help would be greatly appreciated!
