If you want to queue mail for your users, don't do checks that prevents this. Given how MUAs work, you should never defer "submitted" mail. and in general, you should not reject "submitted" mail either, except in few situations. This is one case when bouncing is better. In this particular cas, you should not use reject_unknown_recipient_domain. oh, you forgot to post output of 'postconf -n'...
