False may be the wrong word, and I'm sorry if it is. What I mean is, virtual_mailbox_maps always returns nothing from MySQL, like so: titanus@ntdata:/etc/postfix$ sudo postmap -q t...@nt-backup.dk mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf titanus@ntdata:/etc/postfix$ echo $? 1 (this user exists) titanus@ntdata:/etc/postfix$ sudo postmap -q non_exist...@nt-backup.dk mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf titanus@ntdata:/etc/postfix$ echo $? 1 (this user does not) I did this because I had some trouble constructing the query-string Wietse recommended, and thought this would be a simple and easy way to test if virtual_mailbox_maps was the problem. When trying the syntax within the MySQL CLI, a "Empty set" is returned when querying for a non-existent user mysql> SELECT username FROM mailbox -> WHERE username = 'non_exist...@nt-backup.dk'; Empty set (0.00 sec) I hope this better explains what I meant Cheers
