Why is Webmail in Parallels Plesk Panel 8.1 for Fedora 4 or CentOS 4 not working?
Symptom:
Webmail in Parallels Plesk Panel 8.1 for Fedora 4 and CentOS 4 doesn't work as expected or at all.
Reason:
It is due to a bug in Parallels Plesk Panel 8.1 for Fedora 4 and CentOS 4 after finishing the Parallels Plesk Panel questionnaire the localhost localhost.localdomain entries are removed from your /etc/hosts file.
An example of a broken hosts file would be:
127.0.0.1 ip-10-2-98-190.ip.secureserver.net ip-10-2-98-190
Solution:
Add the localhost localhost.localdomain entries back into your /etc/hosts file.
An example correct hosts file would be:
127.0.0.1 ip-10-2-98-190.ip.secureserver.net ip-10-2-98-190 localhost localhost.localdomain
Note: If you are running Parallels Plesk Panel 8.1 and provisioned or reprovisioned your server before March 7, 2007, you may experience this issue. This Parallels Plesk Panel bug does not affect newly provisioned servers.
