Comment (by strk):

 I think for now it's ok to not support port 587 (submission, optionally
 with STARTSSL) and use port 465 (submissions, using SSL).

 Port 25 is for MTA (mail transport agent) which receives email from a MSA
 (mail submission agent) which receives it from a MUA (mail user agent)

 See:

 The SSL certificate used for mail.osgeo.org belongs to name
 lists.osgeo.org so for now use that name. When/if we change that
 certificate name we will need to update instructions for the submissions
 service on the wiki (no link handy at the moment). For MTA/25/STARTTLS I
 guess it would be useful for the MX record host ame to match the
 certificate name, I didn't check how it looks at the moment
