gnutls-cli fails to handshake with Exchange server that uses DES-CBC3-SHA cipher

[Thomas Fitzsimmons]

Hi,

gnutls-cli --verbose --debug 10 --port 993 "<imap_hostname>"

fails to handshake with my Exchange server, whereas

openssl s_client -debug -port 993 -host "<imap_hostname>"

succeeds.  OpenSSL reports that the server is using the DES-CBC3-SHA
cipher.
