denial of service / space wastage protection.  There's no config option available right now.  I could be convinced to change it.

How would you suggest we protect against exploiting delayed delete to fill the server without going over quota?  Maybe a new quota field for "total mailbox usage including deleted stuff" that can be set to a high enough value that no reasonable user will ever hit it?
