Only defined mail users can register

[Antor]

Hi i know there is a way to decline mail adresses with spesific providers or extensions like @hotmail.com or @*.com etc.
My problem is different
I've to accept only mails like
like *@nigde.edu.tr or *@*.edu.tr or *@*.edu.*

I know my english sucks but i think i made my point clear. Thanks for help.

Sure! Just set up a ban trigger for those email providers that you wish to decline and block them from registration.

The mod has errors. So i couldn't install it.

I want to decline all email providers but @asdasd.edu.tr
All i want to do is it.
