Trouble opening gmail nnimap server in Emacs gnus on Windows

Question

I\'m trying to use Emacs gnus to connect to my gmail account. This is the relevant configuration code, taken mostly from here:

(setq tls-program \'(\"openssl

One thing I needed to do on Windows 7 to connect to gmail from gnus was:

;; So gnutls can find trustfiles on windows
(eval-after-load "gnutls"
'(progn
  (setq gnutls-trustfiles '("c:/cygwin/usr/ssl/certs/ca-bundle.trust.crt" "c:/cygwin/usr/ssl/certs/ca-bundle.crt"))))

Other than that, rest of setup is similar:

(setq gnus-secondary-select-methods
      '(
    (nnimap "gmail"
           (nnimap-address "imap.gmail.com")
           (nnimap-server-port 993)
           (nnimap-stream ssl)
           (nnir-search-engine imap)
           (nnimap-authinfo-file "~/.authinfo")
           )
    (nntp "news.gmane.org")
    (nnfolder "archive"
      (nnfolder-directory   "~/Documents/Text/Gnus/Mail/archive")
      (nnfolder-active-file "~/Documents/Text/Gnus/Mail/archive/active")
      (nnfolder-get-new-mail nil)
      (nnfolder-inhibit-expiry t))))

Able to read mail fine from gmail.

Answer 2

What worked for me is using a gnutls port for windows instead of openssl, and removing any customization of tls-program. Emacs will use the binaries from gnutls automatically if they are on your path since gnutls-cli is the first program to try in the default values of tls-program.

I suggest using gnutls before trying openssl, it probably comes first in the defaults for a reason.
