Hi,
my current setting: parent_domain_matches_subdomains = debug_peer_list,fast_flush_domains,mynetworks,permit_mx_backup_networks,qmqpd_authorized_clients,smtpd_access_maps I'm not using relay_domains, instead it is configured via virtual_maps. It's not under my control because i'm using a configure tool for customers, which generates the maps. But how is this linked to that forward problem, which was the underlying question? Thanks so far. ----- Original Message ---- From: Wietse Venema <wie...@porcupine.org> To: Postfix users <postfix-users@postfix.org> Sent: Fri, February 5, 2010 6:19:30 PM Subject: Re: Weird forwarding problem, what happened?

OK, in that case you could set main.cf: relay_domains= If, on the other hand, you really need to have a non-empty relay_domains setting, you would need to change the parent_domain_matches_subdomains setting from its lengthy default: # postconf parent_domain_matches_subdomains >> main.cf # vi main.cf and delete relay_domains from the parent_domain_matches_subdomains list.
