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:
root@web1 [/var/log]# host btinternet.com
btinternet.com has address 194.73.73.113
and ...
