URGENT - PLease Unblock Email

URGENT - PLease Unblock Email

Hi

I am unable to send emails from james@arnoldpr.com as of 11.30am BST today. I have the message Mail Outgoing blocked. Reason :Mail rate exceeded limit

Please can my email be unblocked ASAP.

I have not sent anymore emails out than usual. I have an out of office on that may be triggering the blocking.

It is business critical that I can send emails within the next hour.

Many thanks for your help

James
