Emails sent to me are getting an error message, and the sender is not sure I got the email - how to fix this?

I used to get my messages without using a password - now, I have to enter the password twice when I open Thunderbird. I received an email from an organization that I subscribed and they informed me that they've taken their list because they kept receiving error messages when they sent me a message. I don't know if that's happening with others but she could be. Do I have a virus, or is there something wrong with the operating system on my computer for Thunderbird? Thanks for any help you can offer

It's your email providers server blocking what he probably considered a hacking attempt. Whatever your email provider is the one with which you communicate.
