smtp port blocked?

I sent some group emails yesterday which I do from time to time. Today I can't get any of my emails on my 4 accounts using smtp.orange.fr to send messages.

Message: An error occurred while sending mail. The mail server responded: 4.2.0 Service refuse. Veuillez essayer plus tard. Service refused, please try later. OFR103_504 [504]. Please check the message and try again.

I have checked with the server "orange" and I can send emails on the internet but not in Thunderbird, so it's not "orange". Please debug this as I need to send some group emails from time to time. Is it the time lapse? Thanks!

Sending via the web mail site does not use the SMTP server so that proves nothing. The error message is from the providers server. Ask them what the problem is.
