I solved the problem ..!!! The problem was not on cyrus, but on postfix configuration.
I see that in the message I have two Return-Path, the first address a cyrus@hostname and the second is the real one. With postfix I solved the problem using lmtp insteas that cyrus transport I use this line in the main.cf file : mailbox_transport= lmtp:unix:/var/imap/socket/lmtp instead mailbox_transport= cyrus The directory of the lmtp socket should be configured where you install the imap directory or smmewhere you configure to put your lmtp socket file. Remember that user postfix should access this file.
