I don't think there's a simple way of allowing arbitrary ports in the
route_data option. If you're willing to have a fixed set of allowed
outgoing ports then you can define a number of smtp transports like this:
port_2525:
driver = smtp
port_252525:
driver = smtp
Then users can just append port_2525 after their list of destination
hosts, separated with white space.
