Sendmail authentication configuration for outgoing mail relay on Solaris

I have downloaded and am attempting to set up a Solaris 10 system to use mail relay for a small number of outgoing emails.  I have an email account and thus a username and password for this provider.

I have set this exact configuration up in the past with different providers but I am running into issues I am unable to resolve.

I compiled and installed sendmail 8.13.8 using the sasl libraries and an appropriate sendmail.mc file

I am attempting to use the /etc/mail/default-auth-info files for holding the authentication data as I have in the past but nothig is working.

Here are some usefull outputs:

RUN FROM LOCAL HOST
sendmail -d0.1 -bv root

         (subdomain name) $m = localdomain

END

I am concerned that I did not get an "AUTH" output line from the telnet.  Thus I am not certain that authorization is enabled.

When I run mailx from the command line I get the following verbose dialog
