smtpmail, starttls and gmail

[Raymond Toy]

After a long time, I decided I should get xemacs working with my gmail
account.  After lots of googling and experimenting, I finally got
xemacs to access my gmail account via imap.  This is working fine.

But I can't send mail using smtp.gmail.com.  Well, it does eventually
send the mail, but I get an error which makes gnus think the mail was
not sent.

My settings from custom.el are

 '(message-send-mail-function 'smtpmail-send-it)
 '(smtpmail-auth-credentials '(("smtp.gmail.com" 587 "toy.raymond at gmail.com" nil)))
 '(smtpmail-debug-info t)
 '(smtpmail-debug-verb t)
 '(smtpmail-default-smtp-server "smtp.gmail.com")
 '(smtpmail-local-domain nil)
 '(smtpmail-smtp-server "smtp.gmail.com")
 '(smtpmail-smtp-service 587)
 '(smtpmail-starttls-credentials '(("smtp.gmail.com" 587 nil nil))

I have gnutls-cli too.

The contents of *trace SMTP* is appended below where I'm sending
myself a junk message.  The message does get sent, though.

Is this a bug in smtpmail/starttls, gnutls-cli, smtp.gmail.com, or
something else?  Surely there must be other people accessing gmail.com
with xemacs!

*trace of SMTP session*, but I deleted the AUTH_LOGIN parts in case
that contains my password.
