Just the usual warning when you upgrade your Rh system to 6.2:
sendmail is installed no matter what, messing up your links in
/usr/lib, and /usr/sbin.
So here what you need to do:
after the upgrade is finished, boot into single user mode (at the lilo
prompt, type `linux 1' or similar). It is really important that you
do not just boot into runlevel 3 5 or 2.
Otherwise the sendmail binary will be started, and will be accepting mail!
So now just do
rpm -e sendmail
ln -s ../../var/qmail/bin/sendmail /usr/sbin
ln -s ../../var/qmail/bin/sendmail /usr/lib
and then reboot.
If after the upgrade, you accidentally boot into runlevel 3 or 5 (or
you do not know how to boot into runlevel 1), sendmail will be
running. You need to stop it first, because the removal of the
package does not stop sendmail. Then proceed as above.
Unless somebody explain to me why, I find it exceptionally stupid
that the sendmail rpm does not stop sendmail upon removal. Apparently,
RH finds this OK. Indeed, see what they say about upgrading to
postfix at
