Ah, Ok. On the current system (running 2.3.3), it does seem to behave as expected (e.g., I've got .google.com and .gmail.com, and I'm not throttling Gmail, which I'm sure would happen instantly if it wasn't matching). $mynetworks is in $parent_domain_matches_subdomains: $ postconf parent_domain_matches_subdomains parent_domain_matches_subdomains = debug_peer_list,fast_flush_domains,mynetworks,permit_mx_backup_networks,qmqpd_authorized_clients,relay_domains,smtpd_access_maps Thanks -- it's very helpful to understand *why* this works. w
