I have a problem sending email out and I can understand your confusion,
Ive never seen this particular problem before:

Apr 4 10:53:51 fedora postfix/smtp[17575]: A057D1258600: to=<mehost.net>, orig_to=<jeffhostname.com>, relay=pop.phnx.qwest.net[63.231.195.31]:25, delay=0.53, delays=0.01/0/0.39/0.12, dsn=5.0.0, status=bounced (host pop.phnx.qwest.net[63.231.195.31] said: 553 relaying denied. (in reply to RCPT TO command))

I have 2 computers on my network at home, a fedora box and an XP
box. If I get my email on my XP box (Mozilla Thunderbird),
and THEN send on my fedora box, I DONT get a bounce,
but if I DONT receieve my emails first, it will fail.
I did these two right after the other. Tried to send via postfix,
failed (above), then received any email from qwest.net on
my XP box, then sent another email on my fedora box (successful):

Apr 4 10:56:16 fedora postfix/pickup[17501]: 8BA6B12585ED: uid=500 from=<jeff>
Apr 4 10:56:16 fedora postfix/cleanup[17588]: 8BA6B12585ED: message-id=<20080404175616.8BA6B12585EDotherhostname.com>
Apr 4 10:56:16 fedora postfix/qmgr[29651]: 8BA6B12585ED: from=<jeffhostname.com>, size=277, nrcpt=1 (queue active)
Apr 4 10:56:17 fedora postfix/smtp[17590]: 8BA6B12585ED: to=<mehost.net>, relay=pop.phnx.qwest.net[63.231.195.31]:25, delay=0.68, delays=0.06/0.01/0.38/0.23, dsn=2.0.0, status=sent (250 ok 1207331641 qp 48901)
Apr 4 10:56:17 fedora postfix/qmgr[29651]: 8BA6B12585ED: removed

This is not a setup issue, rather it seems that qwest.net has
some funny business with having to read my email first in order
to (and Im guessing) verify that Im within their network,
and then it will allow me to send email out.

My postfix config is fine since I can indeed send emails out,
but only after I read my email off qwest.net
