I'm still trying to make offlineimap work with the exchange 5.5 server 
at my office. This time I think I've found something interesting.

offlineimap is adding a message to the IMAP server (maildir->IMAP) using 
APPEND. Operation never ends, and the server times out the connection 
after a while. I've taken a packet trace, and the last two messages 
offlineimap sent where:

......<CR>
<LF><CR><LF>

So offlineimap sent a max MTU sized message (1412 bytes in my case) that 
ended with just CR (no LF). The next message sent by offlinemap only 
has 3 bytes, LF CR LF. Most of the time when offlineimap sends the last 
fragment of the message, it ends with CR LF CR LF all in one message at 
which point the IMAP server replies with an EXISTS message.

Any advice here? Is is just the server that gets mixed up when the CR LF 
CR LF sequence is broken up into multiple messages? Is this even a valid 
message from offlineimap?

Thanks,
Gilles
