So the install went great on my FC4 box, but I cant seem to tell if its running I go to http://myipinternaladdy/zimbra nothing comes up, so Since im new to mail servers, and a Novice with Linux could someone please walk me throught the steps after the install aka the configuration, I looked around the forums but couldnt find anything that really seemed to help Ive seen this thread and used ti to set up it

My host file should I leave it localhost.localdomain localhost
or should I set it to mymachinename.mydomain mymachiine name
I have edited a host file before.
