More postfix stuff – maybe specific to CentOS 7 and Plesk 12.5

Somewhere along the line I started getting these in my mail log:

postfix/trivial-rewrite[51297]: warning: do not list domain in BOTH mydestination and virtual_alias_domains

I found this:

postfix nags about a domain in BOTH relay_domains and virtual_alias_domains, when it isn’t


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


Looking back at older parent_domain_matches_subdomains is not present. No idea why it’s there now but I’ve seen Plesk do funny things – also means Plesk will probably do it again if it really was the cause.

Check postfix config:
