Was it a problem with retry period not yet reached for the domain?
If you try to send emails repeatedly and they fail, then they are put
back in the queue to try again later -- if delivery problems arise, the
time before retrying is extended so that it doesn't keep trying to hit
the server that it couldn't send to again and again and again (too often).
That is... let's say the remote server had some problems, then your
server would retry, but give up and extend the retry period.
