We're running 1.1.4 in production on one machine, and have tried 1.1.5. and 
1.1.6 in our test environment... all three still sometimes have the "next 
message unexpectedly lost" error logged. This happens only for Outlook 
users, and corresponds to the user seeing a message with no subject or body 
in Outlook's list.

Other clients see the message fine. Effective workarounds:

1. Delete index files.
2. Have the user use a client such as Pine to "bounce" the message, or 
reply to it, or etc. After this Outlook can display it. We've sort of 
inferred that this is due to the fact that it's technically a "new" message 
now, as it is rewritten to add the appropriate header fields.

I sent in a bug report with dovecot -n output and etc a couple of weeks 
ago; that info still holds.
