Actually 587 is quite useful: you can set it as an accept STARTTLS/AUTH
only port for all your remote users who would otherwise get their
outbound 25 traffic blocked.
I've never liked the fact that MUA to MTA communication used the same
port as MTA to MTA communication. It just made configuration and
filtering that much harder. 587 is poised to fix this.
