Cannot send mail

Donybruk

I am using yahoo.ca and can login online and send and receive messages. I have been using this for a long time and everything has been working. But now it doesn't allow me to send mail from Thunderbird. It doesn't like the password. I tried the suggestions about deleting the passwords in Thunderbird options but that doesn't fix it.

You may need to 'Allow apps that use less secure sign in'. https://help.yahoo.com/kb/SLN27791.html

Thanks but that was already set. This problem seems to have only started after I upgraded to Thunderbird 52.2.1
