Hi.

I'm looking for a tutorial/how-to for a HSM (Hierarchical Storage Management). keeping old messages for a user in a cheap storage and recent messages in a faster one.

I see on dovecot2 wiki an alternative for hsm as "Alternate storage", but I don't now if it's a good solution for me.

The expected result is a faster imap/pop access for new messages on a "heavy mail users" mailbox, and obviously low cost!

Thanks in advance.
