SpamWall Online Operations Manual

SpamWall Control Panel - Mail Queue Manager
The "View System Mail Queue" option on the control panel will allow you to access the Mail Queue Management System. The Mail Queue Manager allows you to view and manage the emails which have been "queued" on your SpamWall system. This means that they are either waiting to be processed or delayed on the system for some reason, usually because the receiving server is not able to receive the message due to technical or other reasons.Once connected to the Mail Queue Management System you will be presented with a list of all of the email messages (if any) which are currently in the mail queue on your SpamWall system.If there are currently no messages in the queue a "Mail queue is empty" message will be displayed instead. The Mail Queue Manager allows you to view details of any queued messages on your SpamWall system. In addition, if you are looking for a specific message and there are a number of messages in the queue you can use the search feature on the Mail Queue Manager to search the mail queue using various search criteria. These criteria include "Queue ID", "Activity" (Any/Error/Hold/Active), "Sender", "Recipient", "Error", "Size" or "Date".At the bottom of the Mail Queue Manager screen the "Top 10" messages in terms of "Senders", "Recipients", "Sender domains" and "Recipient domains" will also be displayed.Any mail currently in the queue on your SpamWall system will be displayed in the Mail Queue Manager screen in the order which it was received on the system with the most recently queued email messages being displayed at top of the screen. There are various management options available on the Mail Queue Manager which allow you to sort the message records in terms of "Queue ID", "Activity", "Sender", "Recipient", "Error", "Size" or "Date" by clicking on the appropriate heading in the menu bar of the mail queue display. You can also view the actual contents of any messages in the mail queue by clicking on the "Queue ID" of the associated message, which will cause the Mail Queue Manager to open up another browser window and display the contents of the message you have selected. Note that depending on how many messages are in the mail queue it may take up to 30-60 seconds for the Mail Queue Manager to search the mail queue and open up the selected message for display. Note also that it may be necessary to disable any "popup blocker" option you may have set on your web browser or installed on your PC in order to use this feature. If a "Cannot get message contents" message is received when attempting to view an email message in the queue this means that the email in question was either delivered or deleted by the administrator and is no longer in the queue.You can also use the Mail Queue Manager to delete any unwanted email from the mail queue by selecting the check box next to the email(s) you wish to delete and then clicking on the "Delete selected messages" button at the bottom of the Mail Queue Manager screen. Note that for technical reasons the number of messages able to be deleted at any one time is set to 64. If you need to delete more than this at any one time you will need to use the deletion option in the Mail Queue Manager several times until all of the desired emails have been deleted. While logged into the Mail Queue Manager if at any time you wish to see an updated list of messages currently in the mail queue you can select the "RELOAD MAIL QUEUE DISPLAY" button to reload the current mail queue information. In order to log out of the Mail Queue Manager and return to the main interface click on the "RETURN TO MAIN INTERFACE" link.

WHM Scripts

WHM Scripts
When cPanel and WHM is installed, a number of predefined scripts become available in your server’s /scripts directory. You can use any of the scripts simply by typing its location in a terminal session. For example, if you wanted to run the update script, you would type: /scripts/upcp.

Verifying the License

If you suspect that your cPanel and WHM license is not functioning:
Run either of the following commands from your server’s command line interface:
curl -L http://cpanel.net/showip.cgi.
lynx -dump http://cpanel.net/showip.cgi
Next, visit http://verify.cpanel.net.
Enter the IP address you obtained in step 1.
Our website will display the status of your license.
If your server’s IP (from step 1) does not match the IP address on your license, contact cPanel Customer Service for further assistance.
If your IP address matches the license, and you are still experiencing problems, run the following script to verify your license:
/usr/local/cpanel/cpkeyclt
Once the script runs, you should be returned promptly to the command line with no messages if it works properly. If it takes longer than a few seconds, you may be experiencing connectivity issues.

Deactivating the Firewall

If you have a firewall running, you will need to disable it prior to running the cPanel installation. Red Hat and CentOS distributions allow you to disable the firewall during the operating system’s installation configuration. This is the recommended method.
However, this can also be accomplished in Red Hat and CentOS by running the following commands in your command line interface:
/etc/init.d/iptables save
/etc/init.d/iptables stop
The OS firewall must remain disabled in order for WHM and cPanel to run on your web server. When the installation is complete, you will need to configure your firewall using a third-party client. cPanel recommends using APF or CSF.
If you are using FreeBSD, you will need to consult that community’s documentation for disabling firewalls.

Apache Pre-Installation Configuration

Apache Pre-Installation Configuration

Configuring Apache before installation through our EasyApache system is useful during the server’s provisioning process. Accomplishing this task, however, requires that you access another server that is already configured and running EasyApache. There are 2 interfaces you can use to create a new EasyApache profile.
The first utilizes the command line interface. This can be accessed through the ssh command by logging into the server which is already running EasyApache, and typing /scripts/easyapache.
The profile can also be built in WHM under the Software tab by clicking Apache Update.
The 2 interfaces, while they are used differently, present the same set of options.
The EasyApache configuration options range from which versions of Apache and PHP to install to specific security and bandwidth preferences. Your new profile is set up by selecting these options in a step-by-step interface.
When you reach step 5 of EasyApache:
Access the Exhaustive Options List (in either interface).
This will allow your new profile to be created without compiling and installing it on the working server.
Assign a file name, a display name, and a brief profile description to your new EA3 profile.
The Save Only (Do Not Build) option must be used.
This action will store the new profile to /var/cpanel/easyapache/profile/custom/ without recompiling the working versions of Apache and PHP.
Your new profile, once it has been created, needs to be copied to /etc/cp_easyapache_profile.yaml on the new server using the scp command.
Note: Please consult the EasyApache documentation for more information regarding Easy Apache’s configuration options.

Pre-Installation Configuration of WHM / cPanel Settings

To configure cPanel and WHM prior to installation, you can use a command line text editor to create the file /root/cpanel_profile/cpanel.config. By entering a set of recognizable parameters, you will be allowed to configure cPanel and WHM before they are installed. Upon installation, this configuration file will be copied to /var/cpanel/cpanel.config.
The parameters are listed below as a set of variables. The variables are defined in basic terms as “variable name (variable type) (valid input values).” To define a variable, simply set it equal to a value. For example, to set the maximum emails per hour that any domain can send to 500, add maxemailsperhour=500 to /root/cpanel_profile/cpanel.config.
Remember: When using the Boolean variable type, a value of 1 means the feature will be enabled while a value of 0 means the feature will be disabled.

Configuring YUM Before Installing cPanel

It is possible to modify yum (Yellowdog Updater Modifier) prior to installing cPanel/WHM. However, because cPanel handles its own installation of services, you will need to exclude a number of packages.
To exclude these packages:
Open /etc/yum.conf with your preferred text editor in the command line interface.
Enter the following line:
Exclude= apache* bind-chroot courier* dovecot* exim* httpd* mod_ssl* mysql* nsd* perl* php* proftpd* pure-ftpd* spamassassin* squirrelmail*
Warning: Use only vendor-provided distributions when installing cPanel, as cPanel is only tested using these packages. Third-party repositories, such as RPMforge, can replace vital parts of the system and cause unexpected results.
