It is not that my server is getting loaded up because of the mails.
After I limt the number of concurrent lmtp connections I am able to
reduce the db lock errors to a great extent. Now I have set max lmtp
processes as 100 , But what will happen if my user mailboxes grow to
4000 from todays 850 then the mails will be delayed forever. By the time
there will be the next batch to process.

So I thought if there was a way of directly writing to lmtp and to all
mailboxes at the same time I will do better
