I don't think either editions have such a feature. I have Google Apps Premium and I don't see that option. Google's whole mantra is never delete email again!
Google Apps Premium using Postini mail archiving is currently the closest solution. There is no retention period for email in Gmail. If you enable Postini archiving you can then configure a retention period for all email in that domain(s). From the administration panel you can then search and export messages, enable auto-purge, and set the retention period. These features are only available with Premier Edition.
Gmail just give you a set amount of storage and leaves it to the user to manage. The Postini storage is completely separate from the Gmail storage. It is archiving every message and prevents anyone other than administrators from delete items from the archive.
I did not see anything that specifically cleans-up someones mailbox in the Google Apps Marketplace but you might have better luck.
Google Premiere does have some support for policy management, but I don't see any place where you can insist on mail being deleted after x days.

Actually, they have an archiving service available for Premium users so that if you delete emails you can recover from the archive.
I don't know if that service includes a retention period option.
