cPanel Addon

System Requirements

To use the cPanel addon, ensure your system is configured according to the following requirements:

  • Full root/shell access to be able to install the addon
  • cPanel running from stable/release/current versions only (we cannot support edge). LTS versions are not supported
  • The Spam Experts Local Cloud or Hosted Cloud product and admin credentials
  • The "Change MX" feature has to be enabled in the feature list. To do this, select Packages > Feature Manager, click on Edit Feature List and tick the MX entry box. This should be enabled by default
  • PHP 5.4 or above
  • PHP support for:
    • cURL
    • OpenSSL (recommended, not mandatory)

cPanel Server Recommended Setup

Set up optimal protection for the cPanel server:

  1. Log into the Super-Admin or Admin Level Control Panel
  2. Navigate to Users & Permissions > Manage Admins
  3. Select Add to create a new Admin account for the cPanel server
  4. Install the Spam Experts cPanel addon. This can be done via the command line using the following command:

    wget -N && bash

  5. Select Remote Access Key and click Generate New Key
  6. Configure the correct API/MX/user details for the cPanel addon
  7. Disable incoming filters from the Spam Experts servers
    1. For Local Cloud, select Exim Configuration Manager > Basic Editor > Access Lists > Only-Verify-Recipient
    2. For Hosted Cloud, ensure proper delivery from the filtering servers
  8. Run bulk protect from the addon in WHM
  9. Restart Bind:

    /etc/init.d/named restart

  10. For outgoing filtering: Set outgoing smarthost details

A re-run of the installer will not overwrite the addon configuration.

Configuring PHP to support cURL and OpenSSL

The cPanel addon relies on cURL to communicate with the API's it uses. You'll need to ensure both cURL and OpenSSL are supported via EasyApache. The activate this, login as super-administrator to WHM:

  1. Select EasyApache (Apache Update)
  2. Choose Start customizing based on profile
  3. Follow the steps, until the Exhaustive Options List is displayed
  4. Select OpenSSL and CurlSSL, click Save and build

Addon: cPanel

The cPanel part of the addon provides the end user with a (brandable) icon in their control panel, allowing them to view and log into their domains.

The List Accounts section displays a list of domains for which the Cpanel Addon has been installed:

Click the Cpanel orange icon next to each domain, this will automatically log you into the spam filter, where you can manage all antispam settings for the domain.

Addon: WHM

The WHM part of the addon includes all configuration options and features for the Super-admin user.

Upgrade Instructions

The system automatically updates itself (when enabled), and can optionally be updated manually via the web interface. If you experience any issues using the web-based/automatic updater, please contact our support. You can always run the installation command as above to force a new install of the latest version of the addon, all settings will remain preserved.

Downgrade Instructions

  1. If you need to downgrade to an unsupported version, (for example when a WHM version becomes LTS or EOL), you need to use the following instructions. Please note that support for a older version is not supported. This should only be used in emergencies. It is strongly recommended to upgrade your WHM platform to a supported version
  2. Execute the following

    chmod +x
    ./ x.x.xxxxx

    Replacing x.x.xxxxx with the addon version number you wish to downgrade too

  3. Disable the "automatic updates" from the addon settings page

Uninstall Instructions

In case you want to remove the addon, you have to run the uninstaller using the following command:

cd /usr/local/prospamfilter/bin/ && ./uninstall.php

The above command will just uninstall the addon, but all added domains will still be protected as mail will be routed through the Spam Experts system and the MX Records will still point to your Local or Hosted Cloud solution.

To remove all domains from the Spam Experts system and reset the MX Records to their original state from before the addon’s installation, run the following command:

cd /usr/local/prospamfilter/bin/ && ./uninstall.php --resetmx


There are two parts of enabling debug mode, one is enabling debug mode for the addon and the other is to have syslog save debug-level logs. Both steps are required to successfully enable debug level logging.

You can enable the addon's debug mode by entering the following in a terminal:

touch /etc/prospamfilter/debug

This feature should only be enabled when there is a problem and you want to debug it.

To disable it, enter:

rm /etc/prospamfilter/debug

We recommend to enable debugging when there are problems (white pages, unexplainable errors). This mode logs quite some information to the log file and starts displaying more errors in the Control Panel.

Log Debug Level Data

This is very important in the event of any issues you may encounter with your installation. Please follow the below steps to log debug level data:

First, you must change your syslog settings.

cPanel (or CentOS) has a default setup which ignores the "DEBUG" entries.

To make them show up, you can add the following line to /etc/syslog.conf (or /etc/rsyslog.conf) and restart (r)syslog afterwards:

*.debug                              /var/log/debug

To restart syslog or rsyslog, depending on the case, just execute one of the following commands:

sudo service syslog restart

sudo service rsyslog restart

If you want to keep this enabled for a longer period, you might want to add it to the log rotation configuration.

The log will be stored on /var/log/debug.
