Problem syncing from Yahoo! to Zarafa IMAP

[Matthew T. Gibbs]

Hi-

I recently upgraded from 6.5.3 to 6.5.6 (upgraded from openSUSE 13.1 to 13.2, 
Zarafa 7.1.11) and am now having a problem syncing between the above mail 
systems.  When I ran the new version the first time, the local files were 
updated to version two, but the configuration was not changed.  The problem is 
that on Zarafa the messages that are copied from Yahoo! show up with blank 
subjects, senders, and dates and the message body includes the whole message, 
including the header.  The older version worked well, though occasionally 
messages (usually from a particular sender) would have an unknown date but 
otherwise would be okay.

offlineimap is running on the same server as Zarafa and the Zarafa version was 
not changed when the server and offlineimap were upgraded.

I have tried searching for this or similar problems to no avail.  I'm not sure 
how to approach debugging the problem; any help would be appreciated.

Thank you,

Matt
