Block domain email addresses for Contact Form 7 Plugin
Blocks spammers sending contact forms using an email address from the domain of the WordPress installation in Contact Form 7.
This plugin blocks spammers that try to send a contact form with an email address from the domain of the WordPress installation in Contact Form 7.
We have found more and more spammers that use an email address from the domain where the WordPress site is hosted in the form. We don’t want to receive contact forms with email addresses hosted on the domain. For example if the Contact Form is hosted on domain.com they use [email protected] as the email address in the form to try to pass spam validations.
The plugin filters the email address in the Contact Form 7 field:
your-email. If you are giving the email address another name it will not work correctly, so please use the standardyour-emailname.
Please only activate this plugin if you know what you’re doing.
What ideas is this plugin based on?
None. We needed a fast solution to block contact form submissions using dummy email address on the domain where the form is hosted.
System requirements
PHP version 7.1 or greater.
We require 7.1 or higher because we believe that everybody should be running a modern PHP version. When releasing this plugin WordPress recommends PHP 7.4 or higher.

FAQ
We created this plugin to be able to stop spammers from using a email address from the domain where the WordPress site is hosted.
No. The plugin doesn’t write any options or settings to the database.
Install and activate. Try to submit a Contact Form filling in an email address of the domain.
You can simply activate, deactivate or delete it in your plugin management section. There are no options stored in the database so you can delete it also via FTP and everything will be removed.
Please don’t use it with WordPress MultiSite, as it has not been tested.
Yes. The plugin requires a PHP version 7.1 or higher and we recommend using PHP version 7.4 or higher. The plugin has been tested with PHP up to 7.4. When releasing this plugin WordPress recommends PHP 7.4 or higher.
Of course we do. That’s why we created it. 😉
