No, since neither mean anything to an rfc822 mailer in the local part
of an address that contains a '@'.  In local addresses, your mailer may
do anything it wants.  (Including interpreting port of the local
address as another system to send the mail to.)  The
"<@foo,@bar,@belch:user@system>" type of addressing might be usable if
rfc822 didn't specificly allow validating of all system names
mentioned.  (The <> are not optional, this is frequently gotten wrong.)
