As a reminder for me, from http://vspug.com/wkkf/2007/05/09/changing-recipient-of-access-request-for-a-site-emails/
By default SharePoint 2007 automatically configures the access requests for a particular site to go to the person who created the site. This is not always what you want and you may find yourself receiving “Access request for a site” emails for sites you setup, but don’t actually manage. You can change this by doing the following:
- Navigate to the site in question
- Navigate to People and Groups > Site Permissions > Settings > Access Requests
Change the Send all requests for access to the following e-mail address: to the proper address.
