I have a few email aliases for my virtual server and some alias servers beneath it. When I try to send email to those email aliases I get an “Undeliverable Mail Returned to Sender” reply. It says:
(expanded from
): unable to look up host
localdomain.localdomain: Name or service not known
localdomain.localdomain is not a host. I think this should read your FQDN instead.
as in the other thread you do have dns problems that need attention.
check your domains at www.intodns.com
Since I fixed the DNS issues the error is different now. When I try and send mail to info@domain.tld it goes to the mail queue and sits there with this error:
I obviously don’t have my FQDN configured in the right place in Postfix(?). Can anyone point me to the right place to configure it. I’ve looked through every config screen on Postfix, but a lot of it I don’t understand.
