Email Ban Fixes

Email Ban is case sensitif.
Merge pull request #982 from byteGator/Email-Ban-Rules-

Thanks for the pull-request.

If I'm not wrong, strtolower+preg_match is cheaper (faster, less resources consuming) than preg_match with case insensitive. But I think it's more of a hunch than an data-based opinion ;(
