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/sendmail.mx + +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 |
