Thanks for your efforts and tests. I think I found the problem.
The production server we are trying to run on only has 128mb of memory. I can't believe we got a machine with that little, but it happened. I might try running only 2 children of SPAMD, refreshing the processes every 5 messages or so to see if that will work, but I'd say the machine is a little light on the horsepower.
Thanks again!

Ran the test differently and got different results. I sent the 573
messages from a different host. Both the send and the processing in MD
finished in a fraction of the time required for my earlier test.
Everything still seemed fine. What do you think?
