A few answers to the folks that have been helping me:

I took the "p" out of the confAUTH_OPTIONS to allow for encrypted 
user/pass's, and I still get the same error. I tried that a few times in 
my barrage of tests with sendmail.mc :)

I moved the LOG_LEVEL to 15 and I got the following output from maillog:
Feb  4 12:41:59 localhost sendmail[8286]: j14Hf6sq008286: 
ruleset=check_rcpt, arg1=rcurts at robincurts.com, 
relay=wbar15.tmp1-4-8-050-019.tmp1.dsl-verizon.net [4.8.50.19], 
reject=550 5.7.1 rcurts at robincurts.com... Relaying denied. Proper 
authentication required.
(not much help -- just the Proper Auth Required message really)

I did add saslpasswd2 for the user i am trying to log in as, no help 
there either.

When i telnet to my host on port 25 i issue "ehlo localhost" and "auth 
login".  here's the output:
220 intrastudios.com ESMTP Sendmail 8.13.1/8.13.1; Fri, 4 Feb 2005

Note: I have both outlook and thunderbird set to "My SMTP Server 
Requires Authentication".  Outlook tries once and sends me an 
underliverable email saying "Relaying Denied. Proper authentication 
required."  Thunderbird just prompts me over and over for my password, 
until I hit cancel and then it all fails.
