Like?

I haven't tried this, but I thought it should be possible to create a 
(sub)mailbox of a user on a different partition.

If I get the time to try it, we are going to create a new partiton on 
ATA disks, create for each user an Archive folder on that partition and 
give them more quota on that folder.  So we can give our users a limited 
amount of quota in their Inbox and subfolders (these are on fibrechannel 
disks) and more quota on slower disks.

but do correct me if I'm wrong.
