Blocking an entire extension? (Registration)

[Eruantien]

Is it possible to block an entire domain extension from registration? For instance, is it possible to globally block example(at)example.cc (etc...)?

vboptions > user banning options > banned email addresses and enter:
.cc
Email address ban lists: You may ban any email addresses from registering and posting. Type in the complete email address (user@example.com), or use a partial email address (as in @example.com).

Note that partial email addresses are matched from the end of the address unless you enable 'Aggressive Email Banning' below. Therefore if you ban @example.com you will ban user@example.com, but if you ban @example that user will not be banned. If you enable 'Aggressive Email Banning', user@example.com would be banned by @example.

If the email address of a user attempting to register or change their email address matches any of the addresses you specify here will see a no-permission error. For example, if you have banned 'example.com' then a user attempting to use 'someone@example.com' will be rejected.

Put a space between each email address or email address fragment.

Okay, I didn't know if it was that simple. I can just add ".cc" and it will take care of all of it? I don't need to put the "@"?

Thanks Lynn, you're a gem (as usual!)

Yes, you should be able to just add the ".cc", no "@" necessary.
