In addition to the answer of locking the Archive folder, provided by
Michael, consider that requests of this kind often are the result of a
client or customer having a problem for which they came up with the
I hope the machine has a lot of disk space.
Depending on where the machine is, laws may require keeping emails for a
certain period of time, keeping them then purging them after a period of
time, etc. By asking the requester what problem they have that this
solution is trying to solve, you can often get to the root of the
problem and offer a solution that may work better.
Forbidding archive deletion is going to require more work from the
admin, because unless the admin is willing to regularly go through and
manually delete old emails, eventually, the disk will fill up with all
sorts of resulting problems.
Also, consider how this may impact mail server behavior if any quotas
are in effect. Could be a clash.
Depending on what the original problem is, several solutions might be
adding a dummy account and have all emails copied to it, on a separate
drive (NFS, sshfs or dsync, maybe?) or using shared mailboxes.
