I haven't seen any response to this on the list, but am eager to. We have way over a thousand undergraduates and unsophisticates here, and users can exceed their quota by 2 or 3 times. I haven't looked at the problem seriously, but I did notice that the problem doesn't seem to be PMDF specific. Under VMS 5.2, a process with EXQUOTA (or even just SETPRV) can deliver mail to an over-stuffed account via vanilla VMS Mail, where an unprivileged user gets a quota error. The trouble with PMDF (I think) is that the batch jobs run (normally) under the SYSTEM account, extending the "privilege" of delivering limit-exceeding mail to normal users. I'd appreciate thoughts by those more familiar with VMS Mail innards and PMDF. Thanks.
