You might want to see if you are the target of dictionary attacks. This
was happening to my Imail server before I put IMGate in front of it,
because it was under constant load from dictionary attacks. After
IMGate, it runs smooth.
I was experiencing a spike in SMTPD32 memory usage as well. I was running 8.05HF3. I upgraded to 815HF1. Same problem. I checked my logs. We were under dictionary attack from the 207.224.5x.0 subnets. I blocked several class C's and all is fine now.
Lesson: Check the logs!
Cheers
Mark
