[Users] MS Exchange + IMAP = truncated messages

Hello there!

I haven't been able to find any messages pertaining to the subject in
the archive so here goes. One of my e-mail accounts resides on a
Microsoft Exchange 2007 server and I connect to it using IMAP. After
recent changes to the server configuration, I have begun to see from
time to time messages which appear to be badly truncated - not even all
the headers make it through. The problem may or may not be Claws
Mail-specific - while I have seen similar behaviour connecting to the
same IMAP server using Alpine, there are messages displaying correctly
in the latter that Claws sees as malformed. Also, all the problematic
messages look fine in Web Outlook (not having Windows around, haven't
tried standalone Outlook) as well as Thunderbird.

I suspect the problem might be related to the infamous "Enable fast
message retrieval" setting in Exchange which has been known to relax
the server's adherence to the IMAP RFC. A discussion on how this issue
affected Thunderbird, see here:

https://bugzilla.mozilla.org/show_bug.cgi?id=92111

That said, I haven't heard from the admins yet whether the setting in
question is enabled on the server or not.

Anyway, I would greatly appreciate it if you could help me fix this
problem. If you need any additional information, by all means let me
know! Oh, and I run Claws Mail 3.8.0 (as packaged in Ubuntu "Precise")
on a Linux/AMD64 machine.

Best regards,
