To extend my previous message :
I added the option '-o lmtp_destination_recipient_limit=1' to Postfix
and try again to send a message to someone outside my domains, but
adding two people in CC.
It seems that Dovecot is still handling the delivery incorrectly. Here
is the transcript of what happened :

[email protected],n
The last line above shows that, again, Dovecot is trying to read the
email from mailboxe and it launched the 'decypt_mail' program with
user1's params (user1 = '[email protected]'). At this stage, neither
user1 ([email protected]) nor user2 ([email protected]) are
connected and authenticated. Therefore, decrypt_mail is launched without
user1's password (decrypc args are email and user password. In the above
case, user password is set to 'n' because is missing).
Stan.
