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.
To achieve what ?
Postfix has separate "smtp" and "relay" transports for a good
reason.
The scheduler uses round-robin destination selection.
Does this mean "recipient domain" or "transport" ?
The qmgr(8) page doesn't say, and I have learned not to take these
things for granted.
This improves
fairness in the general case, but it bites when you have lots of
mail going to one place, typically, from internet to inside mailhost.
In that case it is better to separate inbound (relay) mail from
outbound (smtp) mail, otherwise inbound deliveries suffer from
competition by outbound deliveries.
How does this work ?
I was under the impression that delivery is balanced between destination
nexthops (as present in the queued message), not between transports.
Or is it BOTH ?
