Migrating to port 587 for AUTH doesn't really seem useful. Unless there is an end goal of separating MTA -> MTA traffic from MUA -> MTA traffic, it seems to me that SMTP AUTH should be used everywhere on port 25...no need to move everything to a separate port except due to ISPs who choose to shut down port 25 usage except to their servers.
