This may not be exactly what you're looking for, but Dovecot natively
supports two level HSM with the dbox/mdbox mail storage formats.
http://wiki2.dovecot.org/MailboxFormat/dbox
Bottom of the page, "Alternate storage". See also:
http://wiki2.dovecot.org/Tools/Doveadm/Altmove
So basically you'd cron a script for some duration (daily, weekly,
monthly, etc) containing the above command to move old mails to your
alternate near line storage.
If it's a really busy server you may want to go with the individual user
route with one HSM script per user. This would allow staggered
scheduling of the cron jobs so as to lessen the load on the server
compared to one cron job which does all users at once.
