This lets your sendmail accept connections from outside to receive mail. 
  I thought your problem was that you were trying to send, but the 
remote was rejecting your invalid domain name.  You need 2 valid 
addresses for internet email, one for the destination and one for the 
sender.

Many ISPs require you to forward email through their relay instead of 
connecting directly to destination servers for delivery, and many, if 
not most destinations will reject direct connections from home-type 
cable or dsl endpoints because there is so much spam from them.  See the 
SMART_HOST entry in your sendmail.mc if you need to let your ISP forward 
for you.
