Connection refused by host.
I have installed zimbra on FC3. It was working. After executing vsftpd, placing some files to /var/ftp/pub/ and removing it, I killed vsftpd process

. After all this extions, I have execute zimbra by '/opt/zimbra/libexec/zimbra start'. Now, if I navigate to "http://localhost.localdomain" FireFox said what connection was refused by 'localhost.localdomain'

. I re-installed zimbra, disable firewall. It is not work.
'zmcontrol status' said what postfix & tomcat are not running.
Tomcat (startup.sh in "tomcat"/bin/ ) said what JRE_HOME and JAVA_HOME are not defined
Please, help me.
