if i send to joe@yahoo.com, the mail goes.
if i send to joe@mydomain.com, mail goes, but i never get.
if i have something sent to storename@mydomain.com, it say in mail logs "<storename@mydomain.com... User unknown>"

i figure, and this is just a guess, sendmail is looking at users in netinfo.

i saw this article and noticed a stop command:
% sudo niutil -create . /locations/sendmail
% sudo niutil -createprop . /locations/sendmail sendmail.cf /etc/mail/sendmail.cf

but i am not sure where to invoke this command. in /etc/mail?
