(bare line feed characters) which the email servers don't support.
I cannot send or forward E-mails using Thunderbird. It started about 10 days ago. The same error occurs when sending E-mails to Gmail.com, Msn.com and other accounts and E-mails addresses. I can send E-mails to myself and then use my cell phone
The following is part of the error message: Thanks.

I want to use Thunderbird Email app which I have used for many years. Is there a Thunderbird add-on that can remove the bare line feeds before the written E-mails are sent or forwarded? I can send E-mails to myself and forward L.L. Bean and Wild Wings E-mails All others fail because of BLFs errors. This problem only started about 2 weeks ago. I do not want to use a browser based E-mail application. They are clumsy to use.
Thank you.
What is your anti-virus software?
AVG
Thank you.

Thank you.
Try to start Windows 10 in safe mode with networking enabled.
Does the problem go away?
Windows safe mode disables anti-virus software. This is a troubleshooting step, not a solution.
