Since few days, every several minutes I get on my mailbox information about new user.
I don’t know what is the main purpose for that but I assume someone is checking something on my site and it not anything good.
Is it anyhow possible to disable specific domain while user is filling email field?
Should I be worried?
BTW you can try this one. I just put together something. It should block gmail.com domain.
This function will check for email domain when someone tries to register on your website and throws an error if email domain is matched.
function wpse_disable_email_domain( $errors, $sanitized_user_login, $user_email ) {
list( $email_user, $email_domain ) = explode( '@', $user_email );
if ( $email_domain == 'gmail.com' ) {
$errors->add( 'email_error', __( '<strong>ERROR</strong>: Domain not allowed.', 'my_textdomain' ) );
}
return $errors;
}
add_filter( 'registration_errors', 'wpse_disable_email_domain', 10, 3 );
OK I just tested it and it’s working.
