How to configure a redhat 9.0 mailserver in a graphical interface
I am facing this challenge of configuring a redhat mailserver in a graphical interface. Kerio has refused to work and I tried to edit sendmail from /etc/mail/sendmail.mc with the m4 microprocessor, but I dont know how to logon to my mailserver in a graphical interface. Please, I seem to have no further idea about this. Can someone quickly help me out? The redhat version is 9.0
And can someone please suggest to me if I really need a DNS registration to get my mailserver graphical interface configured?
