imap connection problems (WinXP / NT Emacs)

imap connection problems (WinXP / NT Emacs)

[John Owens]

I've been running imap happily under Mac OS X for a couple of months.
Now I've moved my setup files over to Windows and during gnus startup,
gnus hangs. This doesn't happen on my Mac.

First, the setup:

NT Emacs 21.3.1 on Windows XP. gnus 5.10.2. openssl is part of cygwin
(updated today). I can connect no problem over the command line:

************ command line:

weetabix 19% openssl s_client -quiet -ssl3 -connect samba3.ece.ucdavis.edu:993
depth=0 /C=--/ST=SomeState/L=SomeCity/O=SomeOrganization/OU=SomeOrganizationalUnit/CN=localhost.localdomain/emailAddress=root@localhost.localdomain
verify error:num=18:self signed certificate
verify return:1
depth=0 /C=--/ST=SomeState/L=SomeCity/O=SomeOrganization/OU=SomeOrganizationalUnit/CN=localhost.localdomain/emailAddress=root@localhost.localdomain
verify return:1
* OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS AUTH=PLAIN AUTH=LOGIN] samba3.ece.ucdavis.edu IMAP4rev1 2001.315 at Mon, 4 Aug 2003 18:00:52 -0700 (PDT)

(maybe the verify error/return is significant?)

************ .emacs:

(if windows-nt-p
    (load "ssl"))
(setq gnus-check-new-newsgroups nil
      gnus-read-active-file 'some
      gnus-nov-is-evil nil
      gnus-select-method '(nntp "news.ucdavis.edu")
      gnus-secondary-select-methods '((nnimap "samba3.ece.ucdavis.edu"
					      (nnimap-server-port 993)
					      (nnimap-stream ssl)
					      ))
      ;; debug
      imap-log "*imap-log*"
      imap-debug "*imap-debug*"
      nnimap-debug "*nnimap-debug*"
)

Maybe

(setq imap-process-connection-type t)

help?

Alternatively, you could try GNUTLS and change the nnimap stream from
ssl to tls.

Same behavior with the patch. Sigh.

I can't think I'm doing something unique here ... surely others run
WinXP and NT Emacs with gnus and nnimap. Is this a known problem? Any
idea why it works on a Mac and not on Windows?
    
    Alternatively, you could try GNUTLS and change the nnimap stream from

I've had zero luck finding a binary (or anything that would compile to
a binary) of starttls.exe on Windows ... a rare beast indeed. So
perhaps with this I will have better luck.
