Network shares with ZFS as file system have the ability (which C&CZ switches on by default) to make snapshots. A snapshot is a read-only copy of the share, made at a specific point in time.

When you are notified that your mailbox is getting full, the preferred response is to clean up, for instance by removing the attachments of the largest e-mails in your Sent folder....
