What is the difference between port 465 and 587? Should I setup SSL for both of them or is one or the other enough?

In December of 1998, R. Gellens and J. Klensin submitted RFC 2476 in support of adding a new specification for internet email communications. The RFC proposed a split of the traditional message submission and message relay concept. The RFC defined that message submission should occur over port 587 to ensure new policy and security requirements don't interfere with the traditional relay traffic over message relay port 25.
