If your problem is that users are leaving mail on server, hashed directories will probably not solve your problem. Hashed directories make directory lookups faster, but actual file reading and writing proceeds at the same pace. The usual problem with users leaving mail on the server is in the reads and writes, not in the directory lookups. Tough quotas (both mailbox size and mail-checking frequency) would help. maildir format might help, if you can get all your other tools and apps to support it. - Morty
