just list all your valid addresses in local_recipient_maps and you are done - in fact there is no need for virtual and what not - it just works that way for some hundret domains over 6 years now and you can do the same with files instead of mysql - the inbound MX in fact creats postmaps files from that data append_dot_mydomain = no parent_domain_matches_subdomains = mydestination = mysql:/etc/postfix/mysql-mydestination.cf local_recipient_maps = mysql:/etc/postfix/mysql-recipients.cf transport_maps = mysql:/etc/postfix/mysql-transport.cf cat /etc/postfix/mysql-mydestination.cf user = dbmailro password = ********* dbname = dbmail hosts = unix:/var/lib/mysql/mysql.sock query = select transport from dbma_mta where mydestination='%s'; cat /etc/postfix/mysql-recipients.cf user = dbmailro password = ********* dbname = dbmail hosts = unix:/var/lib/mysql/mysql.sock query = select alias from dbma_recipients where alias='%s'; cat /etc/postfix/mysql-transport.cf user = dbmailro password = ********* dbname = dbmail hosts = unix:/var/lib/mysql/mysql.sock query = select transport from dbma_transports where mydestination='%s' or mydestination='%d' order by transport desc limit 1;
