Because you exclude this domain from $mydestination, Postfix does not accept mail for it, and the message loops. > The orig_to entry is particularly concerning.

Because mail...@ohnosec.org points to 'mailman', and the result of a virtual(5) mapping is subject to address rewriting. Specifically, when 'append_at_myorigin=yes', Postfix appends '@$myorigin' to addresses without '@domain'. All of this is documented in the virtual(5) man page. And because '$myorigin=$myhostname' by default, your alias to 'mailman' is rewritten to 'mail...@sh.qrvc.com'. > *** postconf -n *** > > [r...@sh ~]# postconf -n > alias_database = hash:/etc/aliases > alias_maps = hash:/etc/aliases, hash:/etc/mailman/aliases > command_directory = /usr/sbin > config_directory = /etc/postfix > daemon_directory = /usr/libexec/postfix > debug_peer_level = 2 > debug_peer_list = 68.99.120.0/24 > html_directory = no > inet_interfaces = all > mail_owner = postfix > mailq_path = /usr/bin/mailq.postfix > manpage_directory = /usr/share/man > mydestination = > mydomain = qrvc.com > myhostname = sh.qrvc.com > newaliases_path = /usr/bin/newaliases.postfix > queue_directory = /var/spool/postfix > readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES > recipient_delimiter = + > sample_directory = /usr/share/doc/postfix-2.3.3/samples > sendmail_path = /usr/sbin/sendmail.postfix > setgid_group = postdrop > unknown_local_recipient_reject_code = 550 > virtual_alias_domains = ohnosec.org,limeylinux.org > virtual_alias_maps = > hash:/etc/postfix/virtual,hash:/etc/mailman/virtual-mailman > > *** /var/log/maillog with peer debug enabled *** Please don't provide verbose/debug logging unless specifically requested.
