 What about the other ports? I would be particularly curious about BCP
 for ports 465 (ssmtp, SSL-wrapped SMTP) and 587 (submission, often
 used for plain-text SMTP with an immediate STARTTLS required).

 Can a case be made for spam reduction by blocking the ports for
 outgoing connections? Are there many systems around that accept
 incoming mail on these ports?

I believe that this is something that should definitely be addressed in a BCP. However, I do not know if this is something that is already covered by an existing BCP -- I'll have to do some searching.
