Hey, I came up with a working solution:
# define mysql maps alias_maps = mysql:/etc/postfix/mysql/alias.cf mynetworks = 127.0.0.1/8, mysql:/etc/postfix/mysql/pop_imap_before_smtp.cf relocated_maps = mysql:/etc/postfix/mysql/relocated.cf transport_maps = mysql:/etc/postfix/mysql/transport.cf virtual_maps = mysql:/etc/postfix/mysql/virtual.cf # smtpd smtpd_recipient_restrictions = reject_invalid_hostname, reject_non_fqdn_recipient, reject_non_fqdn_sender, reject_unauth_pipelining, reject_unknown_recipient_domain, reject_unknown_sender_domain, permit_mx_backup, permit_mynetworks, permit_sasl_authenticated, check_relay_domains, permit broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = box smtpd_sasl_security_options = noanonymous If there are any comments regarding this setup please post :-) Kind Regards, Markus
