Having been on Thunderbird for some years I have suddenly got the following message when trying to send mail.

An (SMTP) error occurred while sending mail. The server responded: Requested action aborted: This mail account has sent too many messages in a short amount of time. Please try later..

I have checked the SMTP server settings in tools, account settings and they are as they have always been. Is there something I have missed?

Ask your email provider. Their server has cut you off for sending more mail than they allow. Thunderbird just delivered the message to you.

If I go to the horde direct I can send as many emails as I like so the email provider has not cut me off but when I send through thunderbird I get the error message.

Sending through web mail is totally irrelevant to using an SMTP server. The message even says it is from the server. Why do you think this is a Thunderbird problem. The provider has put in place measures to keep people from spamming other email recipients using thier SMTP server. You have seen the result of those measures.
