The inbound mail gateways are connected to the internet behind a load-balancing
switch. The majority of the inbound mail traffic is routed to a set of
internal mail servers, also behind a load-balancing switch. The inbound mail
servers are doing a lot of filtering via procmail. We're experiencing
significant delay during peak traffic times.
How can we optimize mail flow from the inbound server to the internal mailbox
servers? One thing we are in the midst of doing is upgrading all the hardware
and software versions to current levels. Based on the config below, what can
we do to increase our throughput?
Insufficient data.
Measure performance to find the bottleneck; otherwise you're
just guessing, and our guesses aren't likely to be much better

For comments on your config, show either "postconf -n" or
"postfinger" output.

Random Advice: Postfix default settings are chosen carefully;
don't twiddle knobs without reading the official
documentation. Don't blindly follow unverified how-tos.
