I have a customer that is trying to send email to a .co domain and every time it fails, shows delayed then fails.

All other email works fine.

I am wondering if it is a DNS issue?

Any ideas would be greatly appreciated.

Best regards

John

I'd determine if it is a DNS issue first. A series of simple nslookup queries run from a command line in the SBS server itself should answer that.

If it is DNS (and I suspect it is), do a bing search using the keywords:

 SBS technet certain top level domains

One of the first hits will be a blog post from the SBS design team for SBS 2008 that describes the issue and has the fix. While written for 2008, it also applies to 2011. I'd just cut and paste the link for you myself, but my phone is being stubborn and I'm not near a PC at the moment,

It was indeed the DNS that was causing the issue, only thing that threw me was I had already applied the registry fix some months ago. I had not however added any forwarders so I used good old Google's DNS servers and now all is working as it should!!

Many Thanks
