Ciao,
I am using Emacs 22.3 and I miss a feature in
"smtpmail.el"; I have checked the CVS version [1] and it
seems to be missing there, too.
I can successfully use smtp.gmail.com:587 to send mail
using "gnutls-cli" to establish the encrypted bridge. With
this server: smtpmail exchanges greetings, then sends a
STARRTLS command, then delivers a SIGALRM signal to
"gnutls-cli" to build the bridge; after this the ESMTP
dialogue goes on. Fine.
With the server relay.poste.it:465 (please do not mailbomb
it) the procedure does not work because it wants the bridge
built immediately, without exchanging greetings. This can
be done by sending SIGALRM to "gnutls-cli" right after the
connection has been successfully established. After this:
the ESMTP dialogue can start as usual with greetings, auth,
etc.
I am not an Elisp programmer, but I guess that the problem
is in `smtpmail-via-smtp' which always tries to send
EHLO/HELO and only after considers a call to
`starttls-negotiate'. The solution should be a customisable
variable that selects the current procedure or an immediate
call to `starttls-negotiate'.
An alternative solution is not to use the
"-s"/"--starttls" on the command line of "gnutls-cli", but
this would require a much bigger change.
TIA
P.S. If more details are needed, please CC me because I am
not on this list.

This is fixed by the introduction of smtpmail-stream-type (which can be
set to `starttls') in the bzr trunk, so I'm closing this bug.
