By default groups are restricted so that only users within your school domain can send emails to them. This protects your users from unwelcome spam messages.

To edit a group so that external users can send emails to it follow these steps.

1. Navigate to smartadmin here

2. Select "Groups" in the Side Menu and Search for a group

3. Select the Group and Edit the Group Posting settings by changing the 'Post Message' Dropdown from the default 'All in the domain can post' to 'Anyone Can Post' and then hit the 'Save Group' Button.

External users can now send messages to that group
