.forward fails intermittently

[Dan Watts]

I'm running IRIX 3.3.1 on a Silicon Graphics Personal Iris.  I've
noticed a problem recently with sendmail and a users .forward file.
It appears that sendmail (or whoever it is that delivers the local
mail) doesn't always use the .forward file.  When mail is sent from
a remote system via an alias on that remote system (user at remote),
the email when it arrives on my system is always put into the
/usr/mail/user mail file instead of being forwarded.  The .forward
is used when mail is sent to user at mysite (or mysite!user).  Has
anyone see this before?  Is there a workaround?

The mail header of one of these nonforwarded email messages is:
