I would much appreciate some assistance.
Months ago, I purchased an email address based on a domain I have. I set it up on Thunderbird, where it has worked just fine, both sending and receiving, ever since . . . until recently
A week ago, I was attempting to send an email from that account when a "Send Message Error" popped up and the email was stopped in its tracks. I'll quote the exact language of the error message, but first it is vital to understand that nothing had changed in email settings or anything else, I had not suddenly sent an email to 10,000 people (or even to 20 people), and I had not sent an email to some odd place. Everything was the same, is the point, but this is what came up:
“Send Message Error
“Sending of the message failed.
An error occurred while sending mail. The mail server responded: [email address] sender rejected. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information AUP#Out-1010. Please verify that your email address is correct in your account settings and try again.”
I went to that site and found the code:
"1010 Code:
“This email account has been blocked from sending emails due to suspicious activity. Blocks will expire based on the nature of the activity. If you’re a Spectrum customer, change all of your Spectrum passwords to secure your account and then contact us.”
This resolved within a couple of hours, and I could again send email, but it happened again two days ago, and it has not resolved. It was the same situation: Nothing any different had occurred that might have been responsible for prompting such a thing.
Email sends fine from webmail but not from Thunderbird. Just to be sure, I called Spectrum tech support and, of course, was told that it was not their email address so call its originator. I checked with the outfit from where I have the domain and from which I purchased the address, which naturally said that it was not their deal because it sent fine from webmail, call the email client. So now I must seek help here.
So, the questions are: (1) What happened to produce supposedly "suspicious activity" and stop outgoing emails? (2) How do I fix it? (3) What needs to be done to prevent this from happening again?
This is Thunderbird 91.3.0 (32-bit). The computer is running Windows 10 Home, version 20H2, OS build 19042.1348
Thank you.
