I don't really understand what the problems would be, if a new port
number isn't used. I think there are concerns that 8-bit text might slip
into the 7-bit only environment. I don't see how using a new port number
would eliminate that, it might even make that more frequent. If I (or
the program) have two port-numbers to choose (one for ASCII messages,
one for 8-bit text), I might accidentally take the wrong one. Then there
is noting to stop that letter. On the other hand, if a single port is
used, but the MTA asks the receiver "can I send 8-bit text" there isn't
any possibility for a configuration or some other error to let 8-bit
text go to unwanted places.
