Route through secondary server for specific domain

[twv]

I have a user that can't send email to a specific domain because that domain is blocking SMTP connections from my server. My server is not on any blacklists and as far as I can tell is not used for any outgoing spam. I have contacted the domain's mail provider but not heard anything back yet.

In the meantime, is it possible to configure exim to route mail to this domain through another server? I have a second mail server that can make SMTP connections to the problem domain.

Yes, exim can be configured to use multiple routers based on lots of criteria, including the domain it's going to. It's all done in exim.conf, which you can customize to your heart's content.

I've never studied just how though; unless someone else writes it for you and posts it, the research and work will depend on you.

Exim documentation may be found here.
