redhat 8.0 configure sendmail

[fshguo]

I am Linux newbie, recently installed redhat 8.0 as a server, anybody give me some idea about what will be the exact command of configure the box to be a sendmail server. or if there is any resource for quick reference.

Q2. I select VNC package in the installation, and how can I active it. so that I can control the box remotely.

Q3. this is a DELL 2400 unit, I don't hear the sound, how can I verify that the sound card is installed properly.

Thank you for your patient.

re sendmail. if its installed, run chkconfig to see if its set to start at boot time.
At the cmd line you can try
ps -ef|grep sendmail
or
service sendmail restart (as root)
