$ postmap -q f...@mydomain.com regexp:/etc/postfix/virtual b...@somewhere-else.tld
Yet, if postfix actually receives a message destined for f...@mydomain.com, I see this log activity: May 21 18:37:02 bks-mail2 postfix/smtp[5803]: C728A1100053:\ to=<b...@myotherdomain.com>, orig_to=<f...@mydomain.com>,\ relay=mx1.myotherdomain.com[<IP>]:25, delay=1, delays=0.36/0/0.26/0.4,\ dsn=2.0.0, status=sent (250 ok: Message 223824627 accepted) Which is confounding. I expected postfix to send the message to b...@somewhere-else.tld as defined in regexp:/etc/postfix/virtual, and clearly some pattern matching did occur because the actual recipient was 'bar'. How is a partial substitution by regexp possible? The only places myotherdomain.com is mentioned are postfix/virtual and postfix/sender_access. Perhaps regexp continues processing postfix/virtual after the first match and also substitutes based on the final catch-all rule? .: postfix/main.cf myhostname = mx1.mydomain.com myorigin = $mydomain mydestination = local_recipient_maps = mynetworks_style = host smtpd_recipient_restrictions = permit_mynetworks check_sender_access hash:/etc/postfix/sender_access reject_unauth_destination local_transport = error:local mail delivery is disabled virtual_alias_domains = mydomain.com mydomain.co.uk virtual_alias_maps = regexp:/etc/postfix/virtual parent_domain_matches_subdomains = debug_peer_list smtpd_access_maps .: postfix/virtual /^foo@/ b...@somewhere-else.tld /^([...@]+)@/ $...@myotherdomain.com .: postfix/sender_access @myotherdomain.com OK @myotherdomain.co.uk OK
