jcoffey-dev is traveling from Thursday 1 October through Sunday 4 October. Issues and pull requests are welcome, and will get an answer after that. Thanks for your patience.
Every way of deleting mail (JMAP, IMAP EXPUNGE, POP3, mailbox removal,
Trash emptying) and Sieve scripts, events, contacts and files now asks
how the account's deletions are kept: a hold keeps them with no expiry
(archivedUntil 9999-12-31), even with undelete off; otherwise undelete's
period applies as before (LH-4).
A hold's date range decides by the item's own date (LH-3). Mail is noted
as held at deletion and settled when it's archived, once its received
date is known; outside the range it gets undelete's deadline or isn't
kept. Events go by their start, with a day's slack for time zones;
recurring events, contacts, files and scripts are held whole.
A groupware item's note now stays until its archive succeeds, and a
failure retries the task instead of being logged and lost (LH-5).
Files, events and contacts are noted when deleted for good and archived by
the unindex task when retention is on; Sieve scripts are archived at
deletion. A restore goes back to its folder, calendar or address book if it
still exists, takes a free " (restored)" name, comes back inactive for
scripts, and is refused over quota with the item left archived.
Acceptance tests 6, 8 and 12.
