Hi Phil!

I have always had a condition in the DATA ACL that rejected
unqualified recipients in the To: header, because a lot of spam that
comes in has simply "To: You" or similar recipients. If a remote
host really wants to use unqualified names, it's not my mail system
that I consider broken.

Set smtp_return_error_details in your configuration file, that should
at least give some meaningful error message back to the sender. You
may also want to set sender_unqualified_hosts to make Exim accept the
unqualified addresses from a few broken, but otherwise accepted,
hosts.
