Error VM521

[arfa69]

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

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.

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

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