Mini Mods - Gmail Registration Fixer

What this Modification does:
If you require unique email addresses, people can still use a Gmail account to register multiple times by placing .'s in the address or by using the @googlemail.com extension. vBulletin will see these as unique emails; however, they will go to the same email. This modification fixes that problem.

Installation:
Just import the product in your Admin CP.

Notes:
If you wish to customize the error message, the phrase is called "gmail_same_email" in the Phrase Manager. You must have the "Require Unique Email Addresses" option enabled for this modification to work.

Updates:
Version 1.01
- Modification now fixes the user+something@gmail.com problem.

I installed and tested this addon but it is only blocking the users trying to use googlemail.com/gmail.com variant. It is not blocking registrations when users are using "." in the email address.

Quite unfortunate.

Unlike back when this Mod was made, today it's really useless to even bother requiring a valid email. Because the autospam programs have defeated pretty much all human verification on the most popular email services. And they get the verification code anyway, directly from your site on pageload after they "click" the submission.. (XRumer)

If you want to stop autospam I would recommend one of the registration time check mods. They're very effective.

I don't even use the email verification anymore, haven't for a little over a year. It's simply obsolete, now.

- doesn't work

This mod has two author's mistakes...

First: Search

$email = str_replace(".", "", substr($vbulletin->GPC['email'], 0, (strlen($vbulletin->GPC['email'])) - (strpos($vbulletin->GPC['email'], "@"))));

Replace it with

$email = str_replace(".", "", substr($vbulletin->GPC['email'], 0, (strpos($vbulletin->GPC['email'], "@"))));

Second: authors mistake - is metodological.... If we have email 'test.1test@gmail.com' in our user database, and we register new email 'test.1.test@gmail.com' - we have successfull registration...

Why?
Because author search (in user database) email 'test1test@gmail.com' (without dots)
