I keep getting
retry time not reached for any host after a long failure period
retry timeout exceeded
when e-mailing aol.com.
I have done some research and it seems that aol e-mail has been pretty shakey in the past, but I am concerned it might be something to do with my server set-up.
But looking at forums, it seems this might be a pretty common issue that just appears and goes away!
What is your experience of sending to aol? Could it be my servers or is it just AOL?
