cyrus + postfix + lmtpd questions

[Diego V]

It did help, thanks Andrew. Found out reading Postfix's main.cf that the use
of lmtp is encouraged instead of the cyrus agent

 Guess the tcp socket is just usefull in a case like yours with multiple
MTAs, right ?

So, to make it short. Postfix and Cyrus comunicate via lmtp and lmtpd
(cyrus) is responsible for mailbox delivery.

Thanks again
