Hi,
I have been reading about prioritizing mail in Postfix on this list. It seems
that the answer is, there is a shared queue and mail is not prioritized. I
want to make sure that I fully understand if this applies to my situation.
All of our servers that send mail go through our Postfix gateways. I don't want
to manage our exchange server as a relay.
I find that when we send out a lot of email and there is mail queued, internal
mail is delayed. I'm assuming the short term solution to this is:
postqueue -s domain.com
Is there another way to prioritize internal mail delivery based on domain?

One huge improvement you can make is to specify the "relay" transport
for incoming mail. That will create a separate queue from the outgoing
mail which is using the "smtp" transport, and will greatly lesses the
impact of a large outgoing queue on incoming mail. You can expand upon
this theme as appropriate.
BTW there are postfix-2.7 and 2.8 rpms available for Centos - 2.3.3 is
ancient and lacking in all of the useful features added since 2003 or
so, you'd be doing yourself a big favor to bring your postfix up to date.
