I had a similar error that was caused by an invalid character in the DNS
records. It drove me nuts for weeks, and I found the problem by accident :-)
Anyway, exim is not nearly as tolerant as postfix and sendmail (based on my
experience at any rate) for bad characters in the DNS records, in this case
caused by someone uploading an updated zone file with international
characters in it. Good luck resolving it.

Subject: [exim] Host lookup did not complete
I have been searching now for around 4 hours for information on the problem
I am experiencing, but as yet I have found nothing to resolve the problem.
First of all, explanation of the problem:
Yesterday, 12/08/05, mail on a customer dedicated server stopped working.
Well, partially. Mail can be sent from the affected domain to any other
domain hosted anywhere. But .. sending to the affected domain name to an
address that forwards onto another address results in the error:
2005-08-13 01:24:51 1E3jpT-0001Rf-73 <= james@???
H=(web1.uh-hosting.co.uk) [213.230.203.64] P=esmtps X=TLSv1:AES256-SHA:256
S=2558 id=154f501c59f9d$5f3c5b00$6401a8c0@arse
2005-08-13 01:24:51 1E3jpT-0001Rf-73 == mailgwd@???
<ben@???> R=lookuphost defer (-1): host lookup did not
complete
So, sending from james@??? to ben@???, once
it hits ben@??? it then forwards onto
mailgwd@??? (Hey, I'd prefer the customer to just use a POP3
account on the server rather than forwarding, but never mind). It seems
during the process of going from ben@??? to
mailgwd@??? it generates the above error.
Now, the machines resolve.conf is fine. Its the same name servers every
other server on our /24 are using and they are not experiencing any similar
problems. dig, host etc .. all work for gameworlddirect.co.uk and for any
other domain name.
Output of exim -bt -d mailgwd@??? is as follows:

Strange, because it can be resolved:

btinternet.com has address 194.73.73.113

I am completely lost with this problem. If anyone needs any other
information let me know and I'll provide it. Any help would be mucho
appreciated.
