OU Distribution List and Security Group Owners may manage the memberships for their groups at http://groups.ou.edu.
- A Distribution List (DL) is a single email address that can be used to distribute an email sent to it to several people. For example, an email sent to "examplelistname@ou.edu" will be delivered to the inbox of every member of that DL.
- A Security Group is a group that can be used to control access to certain services. Security groups may or may not have an associated email address. A common use at OU for security groups is to control access to shared mailboxes often used by departments or student organizations. When a member is added to a specific group that has certain privileges (for example, a group might have access to a shared mailbox), that member will inherit the permission/access provided to the group.
- A Listserv is a separate emailing service available at lists.ou.edu. For more information, visit the What is a Listserv? or Manage a Listserv articles.
