postfix smpt auth no worthy mechs found

[queshaw%sonic.net@localhost]

Hi,

After reading documentation and posts about this common error message, I
have not found a solution.

I am running netbsd 5.1 on x86. I want to send mail through a relay host
(comcast). So, I have installed postfix and saslauthd from pkgsrc with
sasl and tls options.

But, when sending mail I get:

setting up TLS connection to smtp.comcast.net[76.96.30.117]:587
Trusted TLS connection established to smtp.comcast.net[76.96.30.117]:587:
TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)
warning: SASL authentication failure: No worthy mechs found
... (SASL authentication failed; cannot authenticate to server
smtp.comcast.net[76.96.30.117]: no mechanism available)

Do you have any advice, other than keep reading?
