postfix-users: postfix not delivering all by itself (revised que

postfix not delivering all by itself (revised question)

From: Jay G. Scott <gl_at_nospam>

To: postfix-users@postfix.org

a while back i posted to the effect that i couldn't get postfix to deliver
mail all by itself.

it was pointed out that because i had two versions of postfix installed
that i was doing a bad thing. you're right. i've fixed that.
i have ONE version of postfix installed. i compiled 2.7.1 from source.
the OS is redhat enterprise. the MTA is properly set up in
/etc/alternatives.

mail is getting delivered from my test machine (j6).

the MX records from inside the firewall will list ns5 as the lowest
cost MTA.

the problem:
i contend that (and i'm wrong, but don't know why) j6 should relay
this mail directly to vme.arlut.utexas.edu. instead, ns5 is
getting involved. what am i doing wrong?

postconf ... shows that postfix is running w/ the values i put in,
and i've done the postmap or postalias as appropriate on these 4 files.
