I have the following problem : I cannot send mails to more than 100 recipients, I get the following message if I try :

Failed to send message. An error occurred while sending mail. The server replied: Ratelimit "spambombing_limit" exceeded. Please check the message and try again.

It worked fine a few days ago, same for my coworkers. It works for my colleague, he has the exact same configuration as mine. Sending to a group doesn't work either.

Our version of Thunderbird is updated, Windows 10 is updated. Something has changed but I can't find what.

Thanks for your help.

"The server replied:...". You've most likely exceeded a threshold that your ISP set on the server to limit the number of messages sent by a particular sender over a period of time. You (or your IT department) may be able to contact your ISP and have them raise the limit.
