Indeed and if you are choosing a period of 5 years you can just run it at the
end of the year. I do this every year, so I decided to do it after the first
quarter. I have inbox stored on ssd and archive on hdd. (I have some users that
have >80GB mail????). I decided to enable this for specific users by creating
an autoarchive sieve entry. My cron job script checks which users are having
these and then moves the email. I also decided to control to have this done
within specific down hours, so there is no moving done during 'working hours'.
I also made an array of folders to move like common Inbox and Sent Items (yes
these are also getting big), and move these all to a specific year. Apple mail
is even so smart to link inbox emails to archived folders mails in thread view.
This is what you need to build your script around:
doveadm move -u $account Archive/$year mailbox "$mbox" SENTBEFORE $nyear-01-01
SENTSINCE $year-01-01

Clients will just see these folders. Maybe you need to add subscriptions = yes
to the configuration.
