I agree with you but my situation is a little different

I must have explained my problem more clearly, I have got around only 10
recepients per newsletter on an average and there are around 700 such
newsletters to be  delivered. These are news articles people have
subscribed to accourding to interests

Suppose Now I increase the number of lmtp_concurrent connections and if
multiple instances of ltmp are trying to deliver to the same mailbox 
then these mailboxes will get locked , so again There will be lmtp
connections waiting.  I havent tried out increasing the number of
concurrent connections per user because I want to be sure before I
change anything on the live server

Thanks
