Re: Duplicate Mailboxes

Hello,

I'm trying to prevent a situation where someone accidently deletes a
message from their mailbox. I currently make every few hours backups
using rsync.

What I am looking if for messages to be delivered to both the user's
mailbox, and a duplicate mailbox. This way if someone deletes messages,
their duplicate mailbox still has a backup. Then I would use a tool
(archivemail) to periodically delete the old messages from the
duplicate mailbox.

Is there any script that can be used on a global basis for all the
users that can write to both the user and to user.bak ?

Thank you,

Lawrence

It is pretty easy to keep copies of all incoming mail, by adding an
additional delivery address to the arguments for the local delivery
agent. See

http://www.nber.org/sys-admin/copy-in.html

However I should add that we no longer use this method, so it is
possibly obsolete. To keep a separate archive for each user, you might
use something like

A=mail.local -f $g -d $u.bak

in the sendmail.cf. You would still need some program like archmbox to
keep the user archives from growing too large.
