As a manager of a Google Group, you can control who is able to post messages to the group (i.e., send email messages to the group or post to the group's online forum). For example, you can set up your Google Group so that only one of the following groups can email/post to the group: a) anyone, b) only anyone at, c) only group members, or d) only group managers.

The instructions below will help you adjust your Group's settings so that only managers of the group can send messages to members of the group. If a member replies to one of the messages, the message will bounce back (you can also enable replies to go to group managers, only). If the member tries to email the group's email address, the message will also bounce back to the sender.
