[mew-int 3035] Exchange 2010 problems

[Harri Kiiskinen]

Hi,

my organization just moved to Microsoft Exchange 2010, but I'd still
like to continue using Mew. To begin with, the IMAP is turned on on the
server, as Evolution manages to contact and communicate well.

Also mew manages to _connect_ to the server using mewstunnel and
stunnel4, but does not _communicate_.

I tested the server by using openssl:

openssl s_client -connect mail.server.my:993

the connection is set up finely but the commands elicit no response.
However, when using

openssl s_client -connect mail.utu.fi:993 -crlf

to connect to the server, everything works ok.

Now, seeing that 'mew-imap-process-send-string' ends each string sent to
the server with 'mew-cs-eol' which is hard-coded to "\n", I suspect that
the problem lies here. I'm trying to test it further, but setting
'mew-cs-eol' to "\r\n" in .emacs does not seem to fully help. The
communications seems to end ok, but for example the "update folders" 
C-uZ does not actually retrieve anything.

Any suggestions? 

I'm currently running Mew 6.3 from Debian Stable, but if there is a
reason to expect better behaviour from more current versions, I'm
willing to upgrade.
