heh. the subject of my question seems to be wrong.
there's something else i don't understand. here's my postconf -n output:

-----------------------------------------------------
this test box is a mail gateway. i don't deliver mail locally.
it's inside the firewall.
relay_recipient_maps = hash:/etc/postfix/pfknown_users

alias_maps = hash:/etc/postfix/pfmalias
more /etc/postfix/pfmalias
gl: g...@vme.arlut.utexas.edu
i __thought__ that mail sent this way:
mailx -s "test" gl < /etc/motd
or this way:
mailx -s "test" g...@arlut.utexas.edu < /etc/motd
would be sent by this test machine directly to vme.arlut.utexas.edu.
now it's beginning to dawn on me that if alias_maps is for local
delivery only, it contributes nothing to my goal since i don't
do local delivery.
---------------------
http://www.postfix.org/postconf.5.html
alias_maps (default: see "postconf -d" output)
The alias databases that are used for local(8) delivery
---------------------
http://www.postfix.org/local.8.html
The local(8) daemon processes delivery requests from the
Postfix queue manager to deliver mail to local recipients.
---------------------
that is, the relay_recipient_maps entry is okay, it says i can
send mail to gl; and the transport_maps entry is okay. but
alias_maps isn't consulted since i don't do local delivery.
so there's nothing in the above that says gl's mail
goes to the machine vme.arlut.utexas.edu -- alias_maps won't
enter in to it.
is that correct?
if so, what should i do to have this gateway find out about
the connection between the user gl and the mail delivery machine vme?
is that supposed to go in transport_maps? because it seems like
that should be at the domain level only.
what's the syntax in that case?
g...@arlut.utexas.edu relay:[...@vme.arlut.utexas.edu]
or
g...@arlut.utexas.edu relay:[vme.arlut.utexas.edu]
or
g...@arlut.utexas.edu relay:g...@[vme.arlut.utexas.edu]
that is, what do i do about the user name on the right hand side?
i tried the middle one of those, and the mail still goes through
the relayhost.
