Definitely not. Lavabit doesn't do that, and the emails are still now in
the folder on the lavabit IMAP server. If I open the Archive folder over
IMAP with mutt now, there are 9810 messages in there, the same number of
messages that offlineimap began to delete from the local maildir. About
2500 of those messages are missing from the local maildir now, I killed
offlineimap before it could delete the rest.

Interestingly the first message and the last message in the maildir and
IMAP copies are still the same, so the messages that were deleted from
the maildir were apparently in the middle. But offlineimap was certainly
attempting to delete all of them. I'm guessing that it keeps the list of
messages to delete in a Python dictionary and iterates over them, so it
deletes them in a random order.
