My apologies for not phrasing my original response correctly. I should
have said that OptOnline blocks anything outgoing for mail unless it's
to their own servers, or you use a different port.
For example, I have 3 domains that I use mail for. If I try to use my
domain's outgoing mail server on the standard port, the connection gets
refused, times out, etc. If I change the outgoing mail to
mail.optonline.net, it goes out just fine.
If I set my outgoing mail server to my domain mail server on a port
other than the default (IMAP, S/IMAP, etc.), it goes out just fine.
Sorry about the confusion earlier - I was on the phone finding out I've
just been made a partner of another company, so I wasn't thinking too
