   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).

You've repeatedly ignored people telling you to _stop using deliver_
and configure Sendmail to _directly use LMTP to lmtpd_. If you haven't
upgraded to Sendmail 8.12, you should do that as well.

. upgrade to Sendmail 8.12
. follow the directions in install-configure.html#mta to configure
  Sendmail to use direct LMTP delivery

If you aren't going to listen to the advice, please stop asking.
