Which client are you trying to use SSL from?
You can use TLS on port 587, but not SSL.
SMTPS (SMTP over SSL) is deprecated, so you shouldn't use it unless
you have too (Outlook'03 being the only case I'm aware of). If you
need to use SSL with Outlook'03, you should set up port 465 for
using SMTPS the old fashioned way. If you're using Outlook'03 only
on a local network, I wouldn't bother.

is open. Where else should I check to troubleshoot this problem?

If you're having problems with blacklists, TLS/SSL won't fix that.
In order to get around submitters being blacklisted, you have to
either configure the client(s) to use port 587 (the submission
port) instead of port 25, or install spamdyke on your QMT, which
bypasses filters (including rbl checks) for authenticated sessions
on port 25.
Regarding Outlook specifically, it should be noted that Outlook'03
does not support TLS, and can only use SMTPS (the deprecated port
465). Outlook'07 does support TLS however, and should be
configured to use this on the standard port 587.
HTH.
