Mac OS X 10.5 had a great feature that allowed you to use your already created groups as mailing lists. Each group had it’s own mail address (groupname@example.com) and postfix delived each mail to all users of that group
In Snow Leopard Server this feature is not available anymore.
With the help of this scripts you can simulate Leopards group mailing abilities. It creates a postfix alias file out of your LDAP groups (Open Directory) and updates you MTA configuration automatically. You can even exclude groups and use nested groups.
