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 s648499454.onlinehome.us 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
checking:
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 main.cf 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:
