That all depends on whether you have the software already install on your system or not.

Most systems come with sendmail already installed...you can verify by doing a rpm -q sendmail. If its already installed, then you should be able to start up the service. First verify that sendmail isn't already running:

ps -ef |grep sendmail

then do a chkconfig to verify that sendmail is set to start up in the runlevels you're interested in.

chkconfig --list |grep sendmail
should say something like:

sendmail 0:off 1:off 2:off 3:on 4:on 5:on 6:off

which means that sendmail will start on runlevels 3, 4, and 5.

If its not configured to start, then do a 'chkconfig --level 345 sendmail' to configure it to start under those runlevels.

Finally run '/etc/rc.d/init.d/sendmail start' to start up sendmail.

Do the same thing for popper (one of the many pop servers).

Hope this helps.
