Limit JOIN to specific email domains

Does anyone know a way to limit joining of the site to specific @xxx.com email addresses?

that would be of interest to me as well. i am tired of fighting hotmail and their BS. every dolphin site is filtered as sending spam email because of the templated mail system.

THIS IS MORE OF A QUESTION :o) but would it be possible to add the prefix of the mail addy to the list of type that is not allowed to be injected into data base via text ? example            .cn

happy thoughts

You mean suffix?

It sounds like it would work - but where would you do that?

Did you find a solution for  this?
