It turns out there is a variable called "keep" which can be set in the /usr/lib/Mail.rc file which "causes Mail to truncate your system mailbox instead of deleting it when it is empty". If you do this and fix up everyone's mbox, the problem probably won't reoccur very often. At UCB, they tend to be very permissive about things (most mail is readable by all) so I'm not surprised if security seems to be poorly thought out or poorly documented. The "keep" variable IS described in the 2.10 Mail manual, which I can send to interested people. (I have Mail version 2.17, but the manual is only at 2.10.) Phil
