Disabling Throwaway eMail Addresses

Before you use this tutorial, please know that directly within aMember CP is an option to ban any email address you want, including the ability to use wildcards. For example: To disable customers signing up using a freemail.com email address, you can simply enter %@freemail.com inside the “Configuration -> Blocking IP/E-Mail -> E-mail Address” area.

PLEASE NOTE: See bottom of post for massive list of free email domain names.

As an avid aMember Pro user myself, I have come across this question many times – “How do I disallow throw-away email accounts?”, so, I decided to write up a quick tutorial on exactly how this can be done in less than a minute.

If you’re using aMember Pro and you want to stop subscribers from signing up using a throw away email address, simply follow the guide below to do just that.

1. Add the following to your “/application/configs/site.php” file

Am_Di::getInstance()->hook->add(Am_Event::VALIDATE_SAVED_FORM, function (Am_Event_ValidateSavedForm $e) {
    $form = $e->getForm();
    $vars = $form->getValue();
    if (isset($vars['email'])
        && preg_match('/.*?@(.*)$/i', $vars['email'], $m)
        && in_array($m[1], ['gmail.com', 'hotmail.com'])) {
        $e->addError('Sorry, that email address appears to be from an unallowed email domain.');

2. In line 6, change gmail.com and hotmail.com domains to the email domains you wish to block.

3. Add as many domains as you need by inserting additional domains to the array on line 6.


Line 6:

&& in_array($m[1], ['gmail.com', 'hotmail.com'])) {

Now becomes:

&& in_array($m[1], ['gmail.com', 'hotmail.com', 'domain3.com', 'domain4.com', 'domain5.com'])) {

Here’s a few throw-away email providers to help get you started. And you’ll probably want to check back often as I will continue to add additional domains as I come across them.

Please Note: I do not recommend adding them all, obviously, as doing so could cause serious loading issues.
