smtpmail with tls hangs

[Peter Rayner]

This is under emacs-22.1 as provided on FC-8.
Here is the relevant part of .emacs
(setq smtpmail-smtp-server "myhost.mydomain")
(setq smtpmail-smtp-service 465)
(setq smtpmail-starttls-credentials
           '(("myhost.mydomain" 465 nil nil)))

I have both gnutls-cli and starttls installed but have set
starttls-use-gnutls true so it should be  using gnutls-cli
When I send a test message it hangs after the c-c c-c ... When I kill
it with c-g  and look at the *Messages* buffer I see
Sending...
Opening STARTTLS connection to `myhost.mydomain'...done
opened connection ; this last message was an extra diagnostic I added
in smtpmail.el

The smtp trace buffer only contains the "quit" from the c-g.

If I run, from the shell
gnutls-cli myhost.mydomain -p 465
I get
220 myhost.mydomain ESMTP Postfix
and typing
EHLO myhost.mydomain
elicits the usual smtp replies. 

Anyone have any ideas either on the problem or suggestions to track it
further?
cheers
Peter
