Grant/deny access based on a user's email address

[fstorr]

Hi

I'm wondering if I can do this:

I need to grant/deny access based on a user's email address. When a user applies to become a member of a forum, I need to check whether their email contains my company's name. If it does, they continue with the registration process, if it doesn't, then they get denied.

Will I need to edit the source code to do this? If so, how difficult would it be? I know a reasonable amount of PHP, but if vbulletin in written in OO PHP, then I'm probably going to be stuck.

It would require a small modification to change the standard "ban" list ofr email addresses into a "white-list".
