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. -- Stan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
