Limit account applicants with certain email addresses Hi I am working on a website for a student organization of my college. 
In order to prevent spams, I have been looking for ways to limit account applicants only with email addresses from the college but haven't figure out how
In drupal 6 you can use the built in Access Rules to limit user sign ups to certain domains. It can be found at admin/user/rules/add

This no longer exists in drupal 7 because the functionality was moved into a contrib module called User Restrictions
