Automatic Group based on email

[marvinwilliams]

I'm looking for a hack/mod/addon that will allow new registered users to be automatically put in a specific usergroup based on their email address or email domain.

for example:

user1@hotmail.com --> hotmail_group
user5@aol.com --> aol_group
user9@gmail.com --> google_group (no pun intended),

I've seen a few for the 3.x forums, and only seen a few votes, and alot of questions, but no replies.

I'm looking for something that works for 4.x

if you guys (or gals) could point me in the right direction. That would be fantastic and greatly appreciated.

thanks!
