Yes. -- Sometimes I loose track of what I have been doing.

My previous email really refers to gnutls-available-p being
redefined as above. In this case emacs never asks for the username /
password. But I get "Recipient address rejected: Access denied"

Side remark: I also noticed that the info page smtpmail still refers
  to the old code with the outdated variables
  smtpmail-auth-credentials and smtpmail-starttls-credentials.

Using the builtin version of gnutls-available-p I get the
"Key usage violation in certificate" with which I started this
thread. Here I can add another detail:

With emacs 23, I need 

(setq starttls-extra-arguments '("--priority" "normal:-dhe-rsa"))

Otherwise, I get likewise the "Key usage violation in certificate".
This setting has been buried in my .emacs for so long I almost
forgot this. For details, see

http://lists.gnu.org/archive/html/help-gnutls/2009-05/msg00042.html

Unfortunately, there is not too much I can do about the fact that I
need these extra gnutls argument. Anyway, could it be that I would
need to do something similar for the new builtin code?
