Was wondering, how do I backup the emails of all my users? Call me paranoid but having self hosted for 6 odd years now I am transfering my domain & email to Dreamhost. However I would like to be able to take a nightly rsync / backup of the emails.
I’ve tried searching here and the wiki but have not found the right combination of words to turn anything up.
Is this possible? Where are the mails for non shell users kept?
