Subject : LUG: Configuring sendmail to do SMART HOST

Hey Guys,
I was wondering if there were any sendmail experts out there. I am
trying to send mail (mainly logs) to my ncsu email address, from a
fedora 10 box. To do this, i am trying to use the sendmail smart host
feature. However, every time i send a message, it seems to not be able
to connect to the smtp server. I am using the make script in the
/etc/mail folder to m4 hash the config files, and I am restarting
sendmail via the service command in between each make. Here is the
relevant config/log data:

/etc/mail/authinfo:
AuthInfo:smtp.ncsu.edu "U:japage2" "P:123secret" "M:LOGIN PLAIN"

/etc/mail/sendmail.mc:
...
define(`SMART_HOST', `smtp.ncsu.edu')dnl
FEATURE(authinfo)dnl
...

/var/log/maillog after test email...
$>mail -s test japage2@ncsu.[redacted]
...

Any help would be infinitely helpful. I have been hitting my head
against this problem for hours now, and I cant seem to make head or tail
of it. Thank you very much in advance.
