I've recently decided to run sendmail as the primary mailer on my SCO
Unix box, rather than MMDF.  SCO it would seem provides little
documentation or support for sendmail and would rather have you do it
their way..  Well damn the torpedos and full speed ahead. 

I have run into a few problems though in using sendmail.  If I address
mail to a local user (ie: root), it works fine.  If I use full domain
address (ie: root@yqlhost.Cral.CA), it doesn't work, even though it is
the same host.  Also, I've noticed that I can send mail to other systems,
but they can't send to me.   A sample error message follows:

This is a test message..

Can anyone provide any clues?  Please respond via email...

Thanks.
