I composed a message in Thunderbird and tried to send it as addressed. I got a message "Login to server smtp.mailfence.com with user name JoDandurand@mailfence.com failed." This happened repeatedly, even though I checked the password for that server in my account. The message would also not accept my re-entering the server password when asked. The message appeared repeatedly and would not accept the password or send the message. How do I resolve this? Thanks, Jo Dandurand
