Does anyone allow unlimited or extremely large quotas?

Cyrus 2.3.16 doesn't care - it re-packs the whole mailbox every time
mailbox_expunge gets called.

So upgrade to 2.4.x, it's fixed there.  It was a massive amount of work,
and it's not going to backport cleanly.  I've shown mailbox_expunge to
our new Cyrus programmer (Greg) and he asked me to stop before we got
half way through.  It was over a thousand lines of complex code.
