First of all I can get 9-10 messages per second now by move the mail store to a striped hard disk(3 disk strip to one).
I think there are more than one sendmail deliver processes try to deliver to lmtpd. Because when I increase the speed of sending, I will see the number of imapd processes growing. Then I will see a lot of db error 331lockers ect. I know imap can not handle that speed. So more deliver processes doesn't mean good performance. Actrually I am trying to modify the program to limit the number of processes(lmtpd and deliver).

Su - Can you explain how you're measuring this? With sequential sendmail deliveries, or multiple deliveries in parallel? I suspect you'll be able to accept a lot more messages with multiple deliveries in parallel.
