Error Message Auto blocked due to excessive mail

Hi

Please help. Why am I getting this message

SMTP Cannot send message (Email body not accepted due to the following reason "4.7.1 Auto blocked due to excessive mail?

I send one email a week that has 12 email addresses in the email. Its a set of sports results. I get this message and it will not send any other emails once I have sent my sports report. Please help.

The message comes from your email provider. You will need to contact them and ask the reason they are blocking you, and to reset your address for sending. It seems unlikely that they are blocking because the message has 12 recipients, but you never know.
