Prepare sendmail’s certificate
cd /usr/share/ssl/certs
make sendmail.pem
You will be prompted with several questions typical for SSL certificate generation)

Uncomment the following lines to point to your generated certificate
define(`confCACERT_PATH’,`/usr/share/ssl/certs’)
define(`confCACERT’,`/usr/share/ssl/certs/ca-bundle.crt’)
define(`confSERVER_CERT’,`/usr/share/ssl/certs/sendmail.pem’)
define(`confSERVER_KEY’,`/usr/share/ssl/certs/sendmail.pem’)

During upgrade, the following message is displayed: check_hostname Error
The file /etc/hosts should contain the host name and IP address of your server. If it does not, use an editor to modify the file.
Example
127.0.0.1 localhost.localdomain localhost
192.168.1.1 ensim.mydomain.com ensim
Where 192.168.1.1 is the IP address of ensim.mydomain.com
Requirements for upgrading Ensim Control Panel
File system EXT3
Important: Quotas may not function as intended if you use other file systems.
Disk space At least 40 GB
Disk space partitioning:
/ 5 GB or more
(assuming minimum disk space of 40 GB)
/usr 5 GB or more
/swap Twice the size of RAM
The size of the partitions can vary in proportion to the size of the disk space.
/var 4 GB or more
/home 20 GB or more (depending on the number of sites you want to host)
Important: Do not create /home/virtual on a separate partition. The Site Administrator dashboard reports incorrect disk usage if the directory is created on a separate partition.
Installation Checklist
You must install the RPM spamassassin-3 or later on the server before you install Ensim Pro Control Panel.
Verify that you have set up the yum repository containing the operating system RPMs, RPM updates, and RPM extras (required only if using yum to obtain and update RPMs).
Set up a yum repository on your local FTP server or on the server on which you are installing Parallels Pro Control Panel. The installer obtains the operating system RPMs, required RPM updates, and RPM extras from the repository.
