Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Do you have an issue E-mailing Yahoo and aol users?

Recently we've changed IP's as we moved servers, and now had an issue sending and recieving e-mail to and from aol and yahoo users. After thinking this new IP set was blacklisted, or at the very least gray listed, i was scratching my head when it came down to the truth because i myself didnt setup the new box, that infact we were not black/gray listed. After some intensive conversations with the PostMaster of aol, we came to this next conclusion;

Make sure your reverse dns is valid, if it isnt, make sure you have a PTR record in your zone files. A reverse dns is needed for some protocols, such as smtp and pop3.

Also it's not a bad idea to apply for a whitelisting with some of these isp's. It also is not a bad idea to add a SPF records to your dns config as well.

Yes, Some of the servers we manage have similar problem. But only to yahoo not aol. Tried adding SPF, rev dns etc, didnt help. I tried contacting Yahoo, but no reply yet. Let me know if you have any update

UPDATE::::

I forgot to mention, when sending to yahoo, also make sure you check the Bulk Folder, when i got one to work to yahoo, it went to the bulk/spam folder. If the person ad's you to their contact list, they should get them to their main inbox.
