[Dovecot] Wrong message information

[Anders]

We have a few users that every so often get empty data in their message
overview. From and subject are empty, and the date is 1-Jan-1970. When
opening the message in full view, all things are fine. Also, the data in
the actual maildir file is fine.

It looks a lot like the issue described here:

 http://dovecot.org/list/dovecot/2008-March/029282.html

The server is Linux, ext3, no NFS, and Dovecot 1.1.rc4. The few clients
that have had this problem so far have been Outlook Express.

What can be done to debug this?



Thanks,
Anders.
