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.
What is the output for:
# zpool status
perhaps you have a hardware issue?
All good - quite reliable hardware: IBM x3655 dual AMD quad core, 40GB of ECC RAM, 8x IBM 2.5" SAS on battery-backed ServeRAID, RAID 6 and (somewhat pointlessly) ZFS2. All IBM server diagnostics check, full RAM check run without errors, no ECC corrections reported, no uncorrectable errors reported.
