With Google Groups you can create and manage your own mailing lists right from the Google Apps screen. You will need to think carefully about the appropriate controls for each group you create, so you always know who can post, who can join, etc. Follow the guidelines in Creating Google Groups to make sure your groups will work the way you want them to.
