When postfix sends mail to dovecot for delivery, I'm pretty sure that
happens without authentication. It's LMTP via unix socket, not
something an outside client can access directly.
# In 10-master.conf
service lmtp {
unix_listener lmtp {
#mode = 0666
}
}
[ ... ]
# Tell postfix to hand off mail to the definition for dovecot in master.cf
virtual_transport = dovecot
dovecot_destination_recipient_limit = 1
With this Postfix configuration you do not make use of LMTP delivery.
