pub fn forget_account(account: &Account) -> Result<Vec<PathBuf>, String>Expand description
What this device keeps of an account’s mail, forgotten when the account
is removed and you ask it (Microsoft’s accounts, docs/microsoft.md): its
folder of mail when it is Sioul’s own (<data>/mail/<id>; a folder you
chose with maildir = is yours and stays), and what the AI’s reading kept
of it. The folders forgotten come back; an error says what could not be.
