imap not working fine

[din]

I have used the following command to connect to the imap server
through gnus:
(require 'nnimap)
(require 'ssl)
(setq imap-ssl-program "openssl s_client -ssl3 -quiet -connect %s:%p")
(setq imap-authinfo-file (expand-file-name "~/.authinfo"))
(setq imap-debug "*imap-debug*")
(setq gnus-secondary-select-methods
      '((nnml "private")
        (nnimap "MyMail"
                (nnimap-address "zin10.grapper.net")
                (nnimap-server-port 143)
                (nnimap-list-pattern ("INBOX*"))
                (nnimap-authenticator login)
                (nnimap-stream ssl)
                (nnimap-expunge-on-close 'always)
                )
        ))
I get following message:

Also when I run the following openssl command
 openssl s_client -ssl3 -connect zin10.grapper.net:143
I get this result:
CONNECTED(00000004)
36933:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version
number:s3_pkt.c:286:


So Is it Gnus problem or the openssl problem? Also the same imap is
working fine with evolution...
