Or when the regular, trustworthy sysadmin is temporarily replaced by a
crook or is blackmailed or is overridden by a pointy-haired boss.
Indeed it might be valuable protection for the sysadmin who doesn't
want to compromise other people's mail: no need to refuse orders when
you *can't* read them. (New mails can of course still be intercepted
as noted, but that doesn't mean protecting old stuff isn't useful.)

Anyway, this can be done with procmail as well, but a dovecot
plugin might be more convenient.
