+Here's how to remove sendmail from your system.
+1. Find sendmail in your boot scripts. It's usually in either /etc/rc or
+ /etc/init.d/sendmail. It looks like
+ sendmail -bd -q15m
+ -q15m means that it should run the queue every 15 minutes; you may
+ see a different number. Comment out this line.
+2. Kill the sendmail daemon. You should first kill -STOP the daemon; if
+ any children are running, you should kill -CONT, wait, kill -STOP
+ again, and repeat ad nauseam. If there aren't any children, kill
+ -TERM and then kill -CONT.
+3. Check whether you have any messages in the sendmail queue,
+ /var/spool/mqueue. If you do, you will have to try flushing them with
+ sendmail.bak -q. If necessary, wait a while and run sendmail.bak -q
+ again. Repeat until the queue is empty. This may take several days.
+4. Remove the setuid bit on the sendmail binary, to prevent local users
+ from gaining extra privileges through sendmail's security holes. The
+ binary may be at several different locations:
+ # chmod 0 /usr/lib/sendmail
+ # chmod 0 /usr/sbin/sendmail
+ # chmod 0 /usr/lib/
+5. Move the sendmail binary out of the way:
+ # mv /usr/lib/sendmail /usr/lib/sendmail.bak
+ # mv /usr/sbin/sendmail /usr/sbin/sendmail.bak
