Can't send emails all of a sudden

Received this error message after sending one email successfully today" "Sending of the message failed. An error occurred while sending mail. The mail server responded: Mailbox has reached daily sending limits for this IP: 104.61.154.46 (Z22/6017DF6). Please check the message and try again."

This has never happened before. I've been using Thunderbird for years. I've never heard of " reached daily sending limits for this IP" What is up??? Incoming email is fine. It keeps coming in.

PS: I've already researched and contacted my email provider. It's not coming from them.

Then who do you think might be limiting your access to their mail server if not them?

Just to be clear, I checked the IP address https://ip-whois-lookup.com/lookup.php?ip=104.61.154.46&submit.x=59&submit.y=19

Looks like it is the good old Yahoo mail system you will be using. They are reputed to have daily limit of 500 emails, which is 500 email addresses on any mix of mail really. Not truly 500 emails.

But there official documentation simply does not provide and answer. https://help.yahoo.com/kb/SLN3353.html BTW you are paying for a service including support from your ISP. Perhaps it is time they actually provided some. This forum is full of people over the years that can get nothing but nonsense from ATT support because they don't actually employ people to provide support, only read scripts provided to them by an AI expert system.
