My understanding is this is a limitation with active sync in general.

There is no way I know of to make Active Sync use SSL over an alternate port, this is why front end servers need to have provisions to allow SSL traffic from the internet to the Exchange server. And it's also why most Exchange administrators configure it at the same location as the OWA (even though Active Sync doesn't use the OWA service to sync.)

If anyone knows any different I'd be curious to know as well.
