Thank you for your reply. One questionthough, if you add a mount point how do you know what user to move ?

I think I don't understand the question. Dovecot knows where the user's home is, you don't need to guess. With mail_home or with Passdb variables you can define the user's home location and you can use 'doveadm user' to show where the home directory is in the filesystem. However, if you are migrating I would use dovecot sync or similar tool instead of doing the manual process.

I need to move from one mount point to multiple mount points and I'm searching for the best strategy. Right now my take is to script a rsync of the folders that need moving, change dovecot config and restart. In order to do this I need to know in advance what users will end up on the newly added mount point. Thank you for 'doveadm user'. This seems to be the appropriate tool.
