exim config domains?

If localhost.localdomain is set _where_ in exim? And what is a fai?

Sorry, I do not understand at all what you mean. Can you please
re-word? Maybe shell is the universal language. Just give a typescript
of what you do, cat the relevant config files, to give me a chance to
reproduce the error.

(two examples of exim correctly saying "unrouteable" snipped)

So you have a message which is neither the local host nor member of
the list of local domains.

And exim routes the message to the smarthost.

Can you give the complete contents of your /etc/hosts file for this
case please?

What does getent hosts localhost.localdomain say?

Yes, that is correct. The key is what the @ in local_domains gets
expanded to, and I suspect that is only expanded to the unqualified
host name.

Frankly, I think that it should be okay to set localhost.localdomain
as a local domain if you want locally delivered mail. I am inclined to
either close this bug report or to set it wontfix.

Please comment.
