imapsync fails when transferring mails with "application/applefile" attachments

[Ralf Hildebrandt <Ralf dot Hildebrandt at charite dot de>]

I'm trying to sync a mailbox from dovecot-1.2.9 to Exchange 2007
I'm getting 17 errors, and looking at the remaining mails I'm noticing
a common propery:

All mails cotain AT LEAST one attachment of the type
application/applefile

Excerpt from the output during the migration:

++++ Verifying [INBOX.TIR Study] -> [TIR Study] ++++
+ NO msg #11 [hLUKg1N5YLINMrOCl4Wq0Q:223750] in TIR Study

Is this yet another known shortcoming of Exchange 2007?
