Error VM521

I am using thunderbird and I am getting the following when I send emails to stevenage.gov.uk.  This has only just started to happen.  If I send from webmail it appears to be OK.

Sending of the message failed.
An error occurred while sending mail. The mail server responded:
Recipient Domain Invalid (VM521).
Please check the message recipient "addressee@stevenage.gov.uk" and try again

Re: Error VM521

Consider querying with stevenage.gov.uk why their DNS record lacks an A record; this is likely causing the failure observed in Thunderbird.

FYI: the reason why the issue does not occur in webmail is likely due to its use of a different SMTP server that does not replicate the same checks as those performed by the server email clients use.

Re: Error VM521

This has cleared this morning, so I am guessing Stevenge Borough Council were at fault.  Thanks for your help

Re: Error VM521

Glad to read issue resolved itself but the DNS record seems to be the same so unsure what was done to resolve it;
