Yes, it was pretty much empty..actually, I just configured the Dovecot
instance yesterday evening and only tested for "correct operation" by
sending a test mail to myself and login to POP3/IMAP. Pretty much pristine.

And yes, if is FreeBSD ufs.
[wash at jaribu ~]$ mount
/dev/label/rootfs0 on / (ufs, local, noatime, journaled soft-updates)
devfs on /dev (devfs, local, multilabel)
procfs on /proc (procfs, local)
linprocfs on /compat/linux/proc (linprocfs, local)
/dev/ada1s1a on /disk2 (ufs, local, noatime, soft-updates)

Unfortunately, the user has taken the MacBook now so I am unable to test
copying again.

I should be able to test this again at some point next week, but just to
add, I changed the storage to Maildir and I was able to copy all the mails
to the IMAP folder without any issue so I think it's something with SIS.

PS: I wish I could test this with Outlook running on Windows, but I guess
that introduces a completely different environment than what I had on the
MacBook, right?
