I have noticed that mail delivery (from Postfix to Cyrus using LMTP) can be harsh in terms of I/O when several hundreds of messages are being delivered at once. I have local mailing-lists with more than 1 thousand members and when a 500 KB email is sent to the list, the server's load average increases dramatically. This why I use SCSI disks for the Cyrus partition directories, instead of SATA or ATA disks. Now I would like to increase my users mailbox quota from 200 MB to 1 GB. The problem is that SCSI disks are expensive... So I though about the following solution: - Keeping mailboxes default partition mounted on a SCSI disk - Putting each user's sub-mailbox on cheap IDE storage (with symlinks in the mailboxes partition directory) since access to sub-mailboxes is less frequent and less bursty. - Having a cron job that moves messages older than X days from the user's Inbox to a sub-mailbox (on IDE storage) to prevent SCSI disk getting full. Is this symlinking feasible? Or is there another more efficient way to achieve the same goal?
