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


This is my second try at sending this, the first try caused thunderbird to crash with an abort trap from some missing spelling module.

Thunderbird 2 needed a username and password to send SMTP with TLS
Thunderbird 3 refuses to have a username and password to send SMTP with TLS
So now I can send

Which one is broken?
Thunderbird 2?
or Thunderbird 3?
Both?
I would suspect your smtp server (and Thunderbird 2).
Here is why: It is known that Thunderbird 3 will no longer send mail if you entered an username and password and the server does not support smtp-auth. Tunderbird 2 does not care and tries to send anyway, and that is exactly the behaviour you described here.
