That's not an issue with the Debian exim3 package. We've been running
it for years on lots of servers, and I'm really really sure there
isn't an open relay in our network.

It's really hard without logging into your box, running some tests
and looking at the configuration.

Did you by accident, or on purpose, configure exim to forward unknown
local users to a smarthost? That would have this exact same effect.

That doesn't look right. rechnername.domain.com ? domain.com:domain2.com ?
If you want people to look at your config, don't try to obfuscate it.
