This blacklist plugin will automatically check when a user is trying to register to your WordPress site against your backlist function, or defined records of blacklisted or whitelisted domains.

Multiple Domain Filtering Options

The email domain blacklist plugin uses several online methods as well as local plugin lists to detect whether a domain is blacklisted in real time. This means that hackers and spammers will find it hard to register and harm your website!

This is achieved using the following banned domains detector online services:

  1. SpamAssassin - Using a list of free email domains downloaded from SpamAssassin
  2. DNSBL - Using the DNSBL online service
  3. WhiteLists and Blacklists - All this service can be used together with your own blacklists and whitelists domains lists or with your own banned emails list.

Google allows its users to modify the email address by including dots or plus inside the address.

This applies to @gmail.com and @googlemail.com accounts.

Our plugin supports blocking these email variations by adding to the blacklist just a 'clean' version of the email.

The Most Robust Solution
CM’s Email Blacklist was the most robust solution out of all of them in the market, so that’s the one I chose. It’s a ‘world of difference’ fewer spammers than we had before installing the plugin.
