Hello-

Within the past few days, without having made any changes to anything in Thunderbird or this troubled email account, one of my email accounts stopped functioning properly within Thunderbird in two different (and perhaps related?) ways.... 1) Whenever I send an email from this one email account (Comcast POP3 if it matters), I get the following error message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again.

2) Any emails that are sitting in this troubled email account do not show up in the unified inbox, but the other two email accounts' inbox emails show up in the unified inbox.

Not sure why these problems have suddenly popped up as I have been using Thunderbird on this computer for about a year and a half with no issues. I'm able to send email from my phone and other computers from the troubled account, just not from Thunderbird on this computer.

Thanks for your help in advance.
