Having some trouble sending mail to AOL.com. Currently the queue is just sitting there in a retry state. I can't telnet to the MX records for AOL either. Reverse DNS looks fine as well. I'm getting these errors when using the connection tester.
Respond = 554 mtain-me01.r1000.mx.aol.com ESMTP not accepting connections,421 4.7.0 mtain-me01.r1000.mx.aol.com Error: too many errors
If anyone has any suggestions it would be greatly appreciated.
