Check the 'my_destinations' parameter for $mydomain. Make sure this is _NOT_ in the list (it is by default). Reading the tread I suspect you have created a mail loop where postfix gets mail and resends to itself. This doesn't work obviously so it bounces the message.<BR>
<BR>
I suggest you draw a mail flow-chart so you can visualize how the mail should flow. Should your rt server take mails directly? (<A HREF="mailto:rt@host.example.com">rt@host.example.com</A>) or shall all mail be relayed through an existing host (<A HREF="mailto:rt@example.com">rt@example.com</A> via MX server). That's up to you... But here's the magic Postfix formula for the later case. Make sure you enable smtp in master.conf and also don't have any firewalls running.<BR>
<BR>
------------ <snip> -------------------<BR>
<BR>
# For a mail server that does NOT answer mail for other machines or relay mail for<BR>
# other machines $mydomain must NOT be listed. This will create a mail loop!<BR>
#<BR>
mydestination = $myhostname, localhost.$mydomain<BR>
<BR>
# This is the default I beleave... But just in case:<BR>
#<BR>
relay_domains = $mydestination<BR>
<BR>
# If your site has a proper DNS setup you'll have an MX entry for your local domain.<BR>
# In this case, setting this to $mydomain will cause postfix to find your mail server(s)<BR>
# automatically. This is ideal, but change this to the hostname of your mail server if<BR>
# it does not work.<BR>
#<BR>
relayhost = $mydomain<BR>
<BR>
# You need to tell postfix where the aliases are. This file should have your aliases for<BR>
# rt that pipe in to the mail program. Use "dbm:/etc/aliases" on Linux.<BR>
#<BR>
alias_maps = hash:/etc/aliases<BR>
<BR>
# Always fall back to localhost. If you set this to a domain name and want to recieve<BR>
# local mail things will get very nasty very fast.<BR>
#<BR>
mydomain_fallback = localhost<BR>
<BR>
<BR>

Another thing for you to check if this doesn't clear up your problem... You may get a bounce message if RT cannot create a new case due to access rights. If this is true, you'll see a message show up in your Apache error_log.<BR>

bounced with the message: "550 Relay denied" from the exchange server. I'm not
sure if it is getting this from postfix or if It's simply saying Exchange won't
do it. I'm assuming Exchange is the problem. I think I told it to relay for my
hosts, but not sure. Anyway, I'm still looking into that possibility and
wanted to just mention that I'm getting closer.
Any tips on things to check in the postfix main.cf that might cause this?

Maybe I need to setup an MX record on my AD server...
