Imapsync and admin accounts

I’ve been playing around with imapsync - it seems to work fairly well for mirroring IMAP data to a remote mail server.

I want to be able to mirror clients data on a periodic basis - so i want to set this up as a cron job.

imapsync requires authentication to get access to the IMAP source, and I dont want the cron job to stop working everytime a client changes their password.

does anyone know if it is possible to set up an “admin” email account that gets access to all client email accounts, so that i dont need to worry about client passwords, or any work-arounds?
