Getting "rid" of sendmail

[Emmanuel Gravel]

I'm looking for a way to entirely remove an MTA from a box and forward
everything to another host. I've found the /etc/mail/aliases file and
saw that I could configure it so that root would point to something
else, so that's half the battle, possibly. Once that's done, however, is
it simply a matter of setting sendmail_enable="NONE" in /etc/rc.conf to
disable sendmail, or is there more I could/should do, to still keep
having the cron job outputs sent to the place I'd specify in
/etc/mail/aliases?

I mostly don't want the daemon running, but still want access to my
email.

Thanks!
