RE: {bb} BB e-mail notification - bbwarnrules.cfg

[Jerry Shenk <jas@dect.com>]

I think we have a catch 22 here.  The egrep seems to have a problem with the 
[] and sendmail of course needs them.  What I'm doing now is trying to get 
sendmail to read the host name from the hosts file but it doesn't seem to do 
that.  I'm not quite sure why it doesn't pick up the internal IP address of 
the mail server from the hosts file but that's where I am right now.
