How to ask for help: http://www.postfix.org/DEBUG_README.html#mail In particular, we need to see "postconf -n" output and postfix logs of one good session, and postfix logs of one failed session. > > <main.cf> ... > masquerade_domain = > proxy:mysql:/etc/postfix/mysql/mysql_virtual_domains_maps.cf > relay_domain = > proxy:mysql:/etc/postfix/mysql/mysql_virtual_domains_maps.cf the above two settings are probably a mistake. What is the intent of these? > smtpd_recipient_restrictions = permit_mynetworks, > permit_auth_destination, permit_sasl_authenticated, > permit_mx_backup, reject_unauth_destination, reject_unlisted_recipient This is wrong. Don't use permit_auth_destination in this context, and do not use permit_mx_backup. > smtp_mx_address_limit = 0 This should be set at the default 5 or another fairly low number to protect against destinations with hundreds of MX hosts. > smtpd_recipient_limit = 25 Be aware that setting the recipient limit low will increase load on your server. > #mydestination = [He tried a lot of values here, but right now is > empty, and still strange the behavior] Note there is a difference between empty and commented out. Commented out uses the default value of "$myhostname, localhost.$mydomain, localhost" http://www.postfix.org/postconf.5.html#mydestination > show_user_unknown_table_name = no This makes debugging harder.
