You must have a real domain name to send email.  That won't change even 
if you use a different tool to send, and most destinations will reject 
on that basis.  If your hostname isn't set to a fully qualified internet 
domain, tell sendmail to rewrite the outgoing messages with your isp 
email address.
dnl # The following example makes mail from this host and any additional
dnl # specified domains appear to be sent from mydomain.com
dnl #
dnl MASQUERADE_AS(`mydomain.com')dnl

And if this mail is generated as root, you'll want to comment this line 
with a leading dnl:
EXPOSED_USER(`root')dnl
