output = sending only ?
**Sending only... yes.
**DNS is on the same machine, but big deal to move the email off.
**I have MaxQueProc set to 90 right now and doesn't seem to have any affect.
**Spool averages about 800 files (not including log files) which are mainly
retires. We have the retries set for 4 hours.
**CPU utilization? Normal about 8% and normally peaks around 80 to 100%
when sending the load.
**We don't use Web mail.
**The machine only runs MS DNS and IMail. Our WWW and Application servers,
SQL Servers, and Email servers are all on their own machines some clustered
and load balanced.
**I have not seen any errors in the log file. Only normal logging of
connections, greetings, and either successful exchange or notice of full
boxes, users not found, etc.

output = sending only ?
8000 / hr is ridiculous for that machine. I've seen 40K/hour (joke
list delivery) on a P500 / 512 megs RAM (but it wasn't Imail) and the
machine really wasn't sweating.
So something is apparently throttling you.
DNS slowness can certainly hold back deliveries. Your DNS should be
on a machine separate from the mail server. If you're doing a lot of
list delviery (email addressed re-used), then having a big cache on
your DNS will speed lookup as the query ansers will come from local
DNS cache rather than remote NS.
Scott mentioned the number of SMTP processes in memory. If you see
30 or so (I think that's the max default), then maybe you ought look
up the registry hack in the KB to allow more (the joke list server
peaks at 350 SMTP processes, you get the picture?).
Figure like this:
1 msg per 10 secs per SMTP process (rough average)
gives
360 mgs per hour per SMTP process
30 SMTP process x 360 msg/process-hour = 10800 msgs / hour
So with 8000 / hr, your aren' that far off. So if your output is
limited in number of SMTP processes, then 2x or 3x the SMTP processes
should give you a lot more deliveries.
What is your CPU / memory utilization ? Is the machine running only
Imail or have you put SQL2000 in there, too? Do you have 100
simultaneous Web mail connections sucking up the CPU and memory?
Do you have any msgs in the Imail queue? 10's? 100's?
Any errors in the Imail log?
