Hi, In my postfix server, my transport configuration is (thanx again to Simon Matter :-) ) virtual_transport = lmtp:unix:/var/lib/imap/socket/lmtp Do I still need to keep parameter : cyrus_destination_recipient_limit = 1 ? (it seems to be mandatory with cyris deliver, I don't know if I need to keep it with lmtp) Someone from postfix ML told me : "lmtp has support for multiple recipients and per recipient "result". That said, ask cyrus users to confirm that there is no problem with this. " (http://archives.neohapsis.com/archives/postfix/2008-04/0672.html) So...what do you think about this ?
