A particular reply (not to the list) has told me to try:

" Add to service lmtp: process_min_avail = 20 "

And yes, it works (unless for me), so I want to share it with everybody.

Have not exactly measured performance but this morning have seen over 1400 messages/minute with lmtp under heavy load.

What the "process_min_avail = 20" in service lmtp (or anywhere else) exactly imply? cannot find a reference in wiki2 . I suppose it means than 20 lmtp processes are always open waiting for new connections and so reducing startup latency, isn't it?

I had a similar problem, and found the same solution. In my setup, only 1 lmtp process was available and a 2nd one never was created, so the process was really busy. With this parameter (I setup it to 10) I have diferent process and all of them are used.
