On: Mail Data Loss in macOS 10.15

[dv_dt]

Perhaps if the mail database were blockchained or at least merkle tree linked or otherwise metadata secured.

[eli → dv_dt]

Or just backed up.

[nitrogen → eli]

A hash tree for email actually seems like a semi-decent idea for verifying integrity of a synced mailbox.

[journalctl → nitrogen]

So use a hash function like in the olden days.

[nitrogen → journalctl]

The benefit of either a tree or a sequence or hashes is that you could identify where and when the active mailbox differs from the backups. If each message is its own separate file then it's less interesting.
