Hi, when sending an email I am getting the mailed delivery failed with the above error. I have been able to send emails to the same address for years and can still send emails to other addresses. The recipient has confirmed that they can also send and receive emails no problem. I can still send to this address from my hotmail account too, so I know it works. It seems strange that this problem only just started to occur in the last few weeks. Can anyone help please?

The problem is with the Mx record in DNS.

But what server I have no idea, but I am sure the domain is named in the error message. Someone has a defective DNS record, or is enjoying the fruits of DNS poisoning.
