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!
