Not the whole truth. It also depends how you feed mails to lmtp. The default destination_recipient_limit is 50.

So the baseline is : - Use transport maps with "lmtp:" entry to bypass "local" - Raise the "destination_recipient_limit" to more then 50 - Limit the number of concurrent lmtp clients in "master.cf" to something your server can handle Regards Andreas
