For cPanel & WHM 11.46

(Home >> Service Configuration >> Exim Configuration Editor >> RBLs)

 

Overview

You can use the RBLs interface to configure your mail server to check incoming mail against the available RBLs. Your server will block the incoming messages if the IP address or hostname matches an RBL entry.

RBL is short for “Real-time Blackhole List.” RBL servers keep lists of spam-heavy IP addresses and hostnames so that you can easily block them. The WHM interface accesses two RBLs: bl.spamcop.net and zen.spamhaus.org.

 Select RBL options

To select RBLs options, perform the following steps:

  1. Click the RBLs tab.
  2. For each option, select the desired setting, or enter the requested information in the appropriate text box.
  3. Click Save.

Whitelist: IP addresses that should not be checked against RBLs

This option allows you to choose a list of IP addresses to whitelist. These addresses will not be RBL-checked.

Enter one IP address per line in the text box.

 

Skip RBLs on specific domains

To skip RBLs for specific domains, log in as the root user and use your preferred text editor to create and edit the /etc/skiprbldomains file. Add the domains to the file, with one domain name per line.

After you create the /etc/skiprbldomains file, enable the skip_rbl_domains function through the Advanced Editor tab of the Exim Configuration Manager interface.

  1. Click the Add Additional Configuration Settings button.
  2. Select the menu and enter domainlist skip_rbl_domains

  3. In the text box, enter lsearch;/etc/skiprbldomains

  4. Click the Save button at the bottom of the interface.
