messages created in the new folder with the trashed flag

[Alan Schmitt]

Hello,

I'm am seeing several messages in a "new/" folder with the trashed
flag:

# schmitta at top in ~/.Maildir/INBOX [12:16:26]
$ ls -1 new

This seems to pose problems to some mail viewer (such as mu4e), as mails
in the new folder should not have any flag. Is it a bug of offlineimap
that these messages have these flags?

Is there a way to tell offlineimap to not download any message with a
trashed flag?

Thanks,

Alan
