nnimap with openssl stopping up after connecting in Windows (Was: Vista, secure imap and firewalls?)

[Steinar Bang <sb@dod.no>]

I'm changing the subject to make the problem issue clearer.

Steven E. Harris have seen the same problem as me 
 nntp://news.gmane.org/gmane.emacs.gnus.general/67236

He has the problem when using Cygwin openssl, I have the problem when
using SUA openssl.  I believe both operates in unix mode, ie. with LF as
the line separator (rather than CRLF).

Basically the first "openssl s_client ..." command succeeds in making
the connection, but then everything just hangs.  It typically looks like
this in the *Messages* buffer:
 Opening nnimap server on myserver...
 imap: Connecting to myserver.dyndns.org...
 imap: Opening SSL connection with `openssl s_client -quiet -ssl3 -connect %s:%p'...done
 Waiting for response from myserver.dyndns.org...done
 Unable to open server nnimap+myserver due to: Process imap not running
 Unable to open server nnimap+myserver, go offline? (y or n) 
 Opening nnimap server on myserver...failed

I tried the GnuWin32 openssl (in the hope that it maybe used CRLF for
line separations) but it didn't even get as far as the SUA one.  It
didn't even succeed in connecting to the server before it frose up.

When running the "openssl s_client -connect" command from a cmd shell
both the SUA and GnuWin32 openssl programs succeeded in connecting to
the IMAP server.

Steven thinks the solution lies in setting the coding system for the
buffer where nnimaps reads the server responses (perhaps to
undecided-unix...?), but he hasn't yet figured out to do it.

Steven?  Perhaps you can jump in with some more detail here?
