[imapfilter-devel] imapfilter 2.2 broke this LUA function, help?

[Rob Austein]

The following function worked until I upgraded to imapfilter 2.2.
I understand that the underlying problem is that the search results
table format has changed significantly, but it's far from obvious how
to achieve anything like the same result with 2.2.  Which is a pity,
as the ability to do this kind of thing from a nightly cron job has
always been one of the best things about imapfilter.  Any suggestions?


-- Archive old messages.  This is (sort of) a recreation of something
-- that existed in the original 0.x version of imapfilter, rewritten
-- in LUA.  Move old unflagged seen messages to archive mailboxes
-- named using the internal date of the message.  The double inner
-- loop cuts down on the number of IMAP operations.
