I opened the local-host-names file on that server and found
"domain.org"
but not "mail.domain.org". Well, of course not, this is something
that I
usually do manually.
It is looking for "mail.domain.org" because I usually setup the DNS
for
domain names to use a specific mail server address.
I am confused if the "to" e-mail address is supposed to be
"user@xxxxxxxxxx" or "user@domain" or "user@xxxxxxxxxxxxxxx". Only in
the latter case would "mail.domain.org" belong in local-host-names.
From the example above it looks like the server is rejecting the address
"user@domain".
(And to be picky, the MX for domain.org is
sentry.domainbank.com... There is an official set of domains to use in
examples, namely example.com, example.org, etc. I didn't know that
either...)
