Cannot anymore send out email in Mozilla Thunderbird
I have mysteriously newly started getting the following message in Thunderbird.
The message could not be sent using Outgoing server (SMTP) smtp.q.com for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again.
I have not changed any settings for the Outgoing server (SMTP) in years. (The port number continues to be the Default number.)
As a possible remedy, I newly downloaded Thunderbird and then restarted my PC. No luck.
