Bugreport: maxage deleting old email from destination

I mean I am trying on a production server, where I am not allowed to
break everything to test.

Well, this is a bit confusing, because offlineimap syncs both ways, so
I don't see much difference between 'remote' and 'local'. In my case
local is local dovecot and remote is gmail. I am actually interested
in syncing mail FROM gmail (because nothing arrives at the local
server) TO local server. I even tried readonly=1 for gmail repository.
That was for a different purpose - for mail backup. I delete old
messages from gmail but don't want them to delete from my local
(backup) server.

Anyway, I've done what you suggested and now I'm even more confused :).

1. Remove maxage from config. Run the sync. Now I should have all mail
in both gmail and local mailserver. I even installed a mail client and
made a screenshot showing my old mail at the local IMAP server.
Unfortunately I didn't check gmail at this point, but I'm pretty sure
they are the same.

2. I connect to local imap and execute your query to check the
internaldates. These dates seem to match the Date header (checked on a
couple of emails)

. OK Fetch completed.

So we have 133 emails. There are still emails older than 180 days ago
(02-Feb-2011) - we'll check if they are deleted in the next step.

3. I set maxage=180 and rerun the sync.

Syncing 1A_invoices: Gmail -> MappedIMAP
Deleting 26 messages (49, 50, 51, 134, 135, 136, 137, 138, 139, 140,

155, 156) in MappedIMAP[1A_invoices]

4. Trying a local imap FETCH again, still 133 emails

5. Trying a FETCH on a remote imap (gmail)

. OK Success

6. Just to prove I'm not a complete idiot, complaining about the
deleted mail which is not being deleted, I remove maxage and run the
sync again.

at this point it hung somehow (gmail is unstable today, this may be
the reason), so I killed it and started again:

Again, logging in to local imap - 133 emails. Remote gmail - 133 emails.

I don't understand:
- what are negative UIDs?
- what did it delete? The IDs 153, 154, 155, 156 are the most
confusing, because there were just 133 emails in the folder. Are those
different IDs?
- what did it copy? It actually downloaded something, it wasn't just instant!

Now I suspect it's just the debug output which is wrong, but that
needs an explaination anyway. It actually deleted something when I add
maxage and actually downloads something when I remove it. If I just
rerun the sync with the same parameters - nothing happens.
