I've configured postfix as a backup mx server that replays mail to the prim=ry mx that is an exchange smtp server.
These are the settings I've used. 5 relay_domains = . . . the.backed-up.domain.tld 6 smtpd_recipient_restrictions = 7 permit_mynetworks reject_unauth_destination The relaying is working, but something weird is happening. I keep getting t=ese log messages. It says it queued mail for delivery.
