Access rules (email filters)

Have you ever wanted to deny access to all users with a certain e-mail address? Or, better yet, have you ever wanted to only allow users with @institution.edu to create accounts on your site? Below an easy solution using Drupal's access rules.

View your access rules by going to Administer -> Access Control -> Access Rules.

Click on Add Rule and add the following e-mail rules:

• Deny %@% (which blocks all e-mail address)
• Allow %@institution.edu (which will allow people with anyone@institution.edu)

When you're done go and check your rules by clicking on "Check Rules." (Drupal 5)
