Sendmail Daemon On or Off

["Keith O'Brien" <Keith rga com>]

I recently turned off the sendmail daemon on all of my boxes that were just
relaying mail to our exchange server. 

One side effect this had was aliases no longer get translated. So it will
now send mail but anything going to root does not go out. I haven't found
one, but is there a way to alias root to an e-mail address while keeping the
daemon off. 

Also just wondering if most people leave the daemons on and just listen on
the local host or turn off the daemon and deal with receiving root mail in
another way. 

I did a quick google and didn't come up with any answers. 

Thanks, 
Keith.
