Thanks for the leads/tips.  I redoubled my efforts and found this:
http://mail-abuse.org/dul/gateways.htm (RBL apparently is used to 
questions like this...)
also this:
http://www.hserus.net/sendmail.html

Which had this useful bit:
define(`SMART_HOST',`myISPMailserver.com')dnl <--- Your ISP's mail 
server name goes here
MASQUERADE_AS(myISPDomain.com)dnl  <--- Your ISP's domain name goes here
MASQUERADE_DOMAIN(myPersonalDomain.com)
FEATURE(`allmasquerade')dnl
FEATURE(`masquerade_envelope')dnl

This did the trick!

Live and learn, hopefully now this has been posted to the group others 
can find it in the future.

Thanks again,

David
