Add this to exim.conf:


and changing /etc/sysconfig/exim to


(was 60m)

These changes are made near the top of your exim.conf file.

I also found this:

"On a PII 400 with 128M of RAM running Linux 2.2.5, I have achieved
36656 messages per hour (outgoing unique messages and recipients). For
about a 5 minute period, I was able to achieve an average of 30 messages
per second (that would be 108000 m/hour)! We are using: (options that
make a difference):

queue_run_max = 1
remote_max_parallel = 1

We have a cron job hat runs every five minutes that spawns 5 exim -q if
there are less that 120 exim processes currently running. We found that
by manually controlling the concurrency of exim -q processes contending
for the spool for remote_smtp delivery that we gained considerable
performance - 10000 m/hour."
