Description

MailEncryptSavedPreference=1 instructs the Notes Client to encrypt the saved copy of a sent mail (in the Sent folder) and drafts (Drafts) with the user's own public key. As a result, they are stored in the mail NSF in a form readable only to the user – administrators with mere file / replica access cannot see plain text. Use cases are compliance- or trust-sensitive setups in which the mailbox should be shielded from server admin inspection.

Example configuration

MailEncryptSavedPreference=1

Notes & pitfalls

  • Heavily encrypted mailboxes hinder server-side full-text indexing and content filtering.
  • Loss of the private Notes key = irreversible loss of access to the encrypted content; a backup strategy for ID files is mandatory.
  • A value set via mail policy overrides a local entry.
  • Pairs with MailEncryptOutgoing and the encryption configuration in the Person document.
