Subject: Re: [exim] Urouteable address when send from remote host
Hi,

I think the output show’s what I’m suspecting, it has something to do with local_domains and the routing of it, but I don’t know how to solve it, I’m probably missing some crucial info on the inner workings of Exim (I’m new to Exim, I normally run postfix, but sofar I like what I see, despite the problems ;-)).

> exim -bh ip.of.remote.server


I’ve run this command twice, once with the domain in local_domains+relay_domains, the second time with the domain only in relay_domains

The following data is used:
- exim.conf from the last mail
- remote server: mail.somedomain.com [x.x.x.x]
- remote e-mail: user@???
- local user: my.user@???:
- local server mail.example.com

local_domains+relay_domains:

# exim -bh x.x.x.x
