DNS (/EXIM) issues - detailed

[n3tph4t]

Long time listener 1st time caller:

I have spent the last 3 weeks trying to resolve this issue and don't feel any nearer.


My setup:
DNS is off-site, no DNS is done on the box. My DNS servers in WHM are those of my external DNS.
Everything is runs on the cpnael box. BIND is turned off.

My problem:
Remote mail is delivered to the internal server fine (receive fine)
Internal mail is delivered to the internal server fine (send and recieve fine)
Remote mail is undelivered to the remote server (send fails - sits in mail queue)

Exim Main Log (there are hundreds of these):
2007-02-16 17:15:45 1HI6fZ-00020i-7t == user@replaced.com R=lookuphost defer (-1): host lookup did not complete

My resolve.conf (IP's kept in to help, will remove if of no use):
nameserver 209.59.193.17
nameserver 64.246.165.245
nameserver 69.28.244.50

after reading a similar problem I then added these - not sure of the usefulness
domain darkorb.net
search darkorb.net
nameserver 66.197.217.11
nameserver 66.197.217.12



So far today I have done the following:
tail /var/log/exim_mainlog - to see what was going on (no extra info)
mkdir /etc/eximbackup - backup exim perl file
mv /etc/exim.pl /etc/eximbackup/ - backup exim perl file
/scripts/eximup --force
/scripts/convert2maildir
/scripts/courierup --force
/scripts/upcp --force
pico /etc/localdomains - to see if there was anything funky here there wasn't
dig mx yahoo.co.uk - host not found
traceroute yahoo.co.uk - host not found
pico /etc/resolv.conf - contents given above
/scripts/updatenow
/scripts/updateuserdomains
tail /var/log/exim_mainlog


I'm a cpanel n00b, I have had it for ages but interact with it very little, I don't think these issues are caused by cpanel/whm but if they are not then they may well be beyond my (very limited) DNS ability too.

I would appreciate any/all help offered. I have searched every thread which relates to similar issues to no avail. If anyone is in the UK and thinks they may be able to help, I would also be happy to call them and reimburse them for their time.

Many thanks


PS - I have tried to include any information which may be helpful, if there is anything ele I can add, please ask and I will endevour to get it for you.

Do you have any firewall installed? This is strange because you cannot even do a dig lookup

[katmai]

did you manage to get any fix for this?
