Adding DomainKeys using 123-Reg

Has anyone managed to add DomainKeys and Sender ID using 123-Reg. I have followed the advice on this web page but Campaign Monitor does not want to Authenticate them.

Can anybody help?

Thanks Gavin

Have you tried doing a TXT record lookup on your domain at (as per )?

That will show you if the records are actually there or not.

Does not look like they are there. Is the next step for me to contact 123-Reg for assistance?

Gav, I just double checked too and can confirm the record isn't there. I'd recommend contacting the 123-Reg support team and ask them to make sure they've added the record correctly.

I might be wrong here but looking at the whois record for shows the nameservers on a different server that the 123-reg servers.  The only way the DNS control panel will work on 123-reg is if the nameservers are with 123-reg.  Otherwise you will need to add the TXT record to your zone file on the server.

I fell foul of exactly the same thing yesterday trying to create an A record for a domain on 123-reg when the nameservers are pointing somewhere else.

As I say, I might be wrong.

I am trying to add those records to a domain in 123-reg today also.
I set them up in 123 a couple of hours ago.
They are now appearing in DNS stuff see here

The SenderID has authenticated in campaign monitor but the domainkey hasn't.

I use @ in the name field in the 123 DNS area.
I don't think that will work OK for domainkeys, but 123 doesn't seem to allow dots(.) in the name field, which would mean we can't authenticate domainkeys with 123.

Anyone else managed to do this?

Tim and Gav, if their admin tool doesn't allow you to add a name with a dot, you'll need to fire their support an email ask them to add it for you manually. Most ISP's are usually more than happy to take care of this.

I think I should point out that Dave is actually on his honeymoon in the Maldives right now.

Dave, step away from the computer and give your new wife the attention she deserves!!

Hope married life is treating you well Dave.

Wondering if 123-reg ever sorted this for you as I'm having same problem.

As far as we know Russel, 123 still has the same restrictions on their front end. It may be possible for them to manually fix it for you though.

I gave up in the end, if you get a result it would be nice to know.
