No. My best guess is that (your) ZFS+FreeBSD is simply not behaving the way Dovecot wants filesystems to behave (readdir() sometimes skipping over files). I don't have any other suggestion than trying a different filesystem or OS. I haven't heard ZFS having these problems before though.
Or migrating to sdbox. Absent any further suggestions, that will be my next step. My commitment to Maildir is far lower than my commitment to FreeBSD/ZFS. It is just a historical preference coming from a decade+ of courier IMAP.
Actually as a workaround you could try maildir_very_dirty_syncs=yes which gets rid of most of the readdir()s.
