I've got a customer that is getting an error sending to a specific domain only as far as we can tell.

When I look up the issue it suggests that the MX records are not set up properly but they appear to be fine. Below is the error...
I've change the names. The email was sent to the main recipient [email protected] and cc'd to [email protected]

There is nothing that stands out to me.. These are all the yellow points and the blue for MX

WARNING: Looks like the parent servers do not have information for your TLD when asked. This is ok but can be confusing.

Different autonomous systems: WARNING: Single point of failure

Your SOA EXPIRE number is: 3600000. That is NOT OK

WARNING: Not all of your nameservers are in different subnets


Your MX records that were reported by your nameservers are:
0 mail.domainname.co.uk 12.123.12.34
[These are all the MX records that I found. If there are some non common MX records at your nameservers you should see them below. ]


OK. Looks like you only have one MX record at your nameservers. You should be careful about what you are doing since you have a single point of failure that can lead to mail being lost if the server is down for a long time.

Could you submit a ticket for us to investigate further? We'll need to have the actual email address to investigate, which isn't possible via the forum. Right now, I'm uncertain about the TLD failure message at the parent nameservers. Not having that existing sounds like an issue to me, but without seeing the domain and email to check, I cannot say that's the source of the issue or not.

Tickets can be submitted using WHM > Support Center > Contact cPanel or using the link in my signature.

This issue has been solved.. I'm not sure what the exact cause was but there was an issue with the dns cluster which has now been fixed and I think solved it. I've made a few changes that may of had an affect.
