I enabled smtps because I thought that was the issue, but it still will not work. Here's the mail.log file:

It shouldn't be anything with my network, so what is the problem?
EDIT:
There seemed to have been something wrong with my main.cf
and once I set it back to my defaults everything worked.
Best Answer
Yes, it's refusing port 587 because the entire section of
master.cf
is commented out.Uncomment this if you want Postfix to accept mail on this port.
