I am going to continue this on ports, my mistake earlier I created a new profile, but I still can't get thunderbird 3 to accept my self-signed certificate for sendmail TLS. It asks for me to confirm that the certificate should be used as a permanent exception (just as previous thunderbird did at first setup or after making new certificates on my server.
Sending of message failed. An error occurred sending mail: Unable to authenticate to SMTP server bennettconstruction.us. It does not support authentication (SMTP-AUTH) but you have chosen to use authentication. Uncheck 'Use name and password' for that server or contact your service provider. I am unwilling to use an email system without encrypting passwords since these are valid usernames on the server. I have no problem receiving mail
