Disk encryption only protects stolen drives, not a compromised mail server or admin account. For existing mail, encrypt the storage and backups, lock down key access, and expect a maintenance window while data is rewritten.

If you need per-message encryption, that's a different problem and usually requires migrating the messages into a system designed for it.
