<DKIM> Re:[offlineimap] Duplicates of messages copied from remote to local (#174)

A long time ago, in a galaxy far, far away.... I was attempting to do a
git bisect on an intermittent issue I am having with OfflineIMAP. The
symptom, is that once every now and again (sometimes days between
issues, sometimes twice in one day), OfflineIMAP would redownload the
entire folder, creating duplicate messages. I would then have to remove
duplicates (usually by asking Mutt to tag them using ~=).
I attempted to do a bisect before, but messed something up, and ended up
in an unlikely commit.
I've finally finished another bisect process. Note that since it's an
intermittent and seemingly randomly triggered issue, I marked a commit
as good after about a week or two after using it with no problems. So it
is possible there is some uncertainty in the process.
This time, I ended up at this commit being the first bad one:
Now to me, this looks quite plausible, because the comments refer to
forgetting everything we know about messages.
This happens against both a Dovecot IMAP server and an Exchange server
working in IMAP mode.
I hope this is of some help.
