Transaction failed

Hi all, I read some msg about the error below, but my PTR (reverse) of my smtp mail server is correct and I don´t know why I still receive this error… any help ? In time, my server is not in AOL spam database…

“Error transferring to mailin-03.mx.AOL.COM; SMTP Protocol Returned a Permanent Error 554 TRANSACTION FAILED”

ps- The problem occurs only with AOL.COM.

Hi,

seems your server is blocked at aol. We had a simmilar problem a few month ago when we try to send mails to that company. They where blocking connections from servers within a certain ip adress range. Thry to find a contact at aol.
