imap and openssl on Windows

[Holger Sparr]

Hi,

I have problems to read my mail:

.gnus.el

(setq gnus-secondary-select-methods '((nnimap "xxx"
(nnimap-address "imap.server.de")
(nnimap-server-port 993)
(nnimap-authenticator login)
(nnimap-stream ssl)))

There will be no server response to the imap command send.

*imap-log*

| * OK The Microsoft Exchange IMAP4 service is ready.
| 1 NOOP
| * BYE Connection is closed. 13
| done
| depth=2 C = DE, O = DFN-Verein, OU = DFN-PKI, CN = DFN-Verein PCA Global - G01
| verify error:num=20:unable to get local issuer certificate
| verify return:0
| read:errno=0
| 2 CAPABILITY

In contrast, connecting to the server via command line with cmdproxy.exe I get:

cmdproxy.exe "openssl s_client -connect imap.server.de:993"

| * OK The Microsoft Exchange IMAP4 service is ready.
| . noop
| . OK NOOP completed.
| . logout
| * BYE Microsoft Exchange Server 2007 IMAP4 server signing off.
| . OK LOGOUT completed.
| read:errno=0

I tried several settings for imap-client-eol and several addtitional flags for
openssl through imap-ssl-program.

Do you have any ideas?

Thanks in advance.

It looks like the MS Exchange server doesn't understand tagged commands,
which is really weird.

Anyway, nnimap has been rewritten completely in the development version
of Gnus/Emacs, and it's been reported to work with MS Exchange, so this
may or may not work now if you install development Gnus.
