smtpmail with authentication problem

[FCC]

Hello all,

I am posting this to gnu.emacs.help because I could not get an answer to 
it at gnu.emacs.gnus.

I can read news and check my e-mail using gnus. I have been trying to 
send e-mail using

GNU Emacs 21.3.1 (i386-msvc-nt5.1.2600) of 2003-03-28 on buffy

I have also tried to use the smtpmail.el and sendmail.el of latest CVS 
emacs, because I have found posts claiming that those files shipped with 
Emacs 21.3 do not have authentication support. In my server, I 
definitely need authentication (for example in Mozilla I must use 
authentication or I cannot send any mail).

But I have no success.

Here is what I have in my _emacs:

(setq user-full-name "myname")
(setq user-mail-address "mylogin@mydomain")
(setq message-send-mail-function 'smtpmail-send-it)
(setq send-mail-function 'smtpmail-send-it)
(setq smtpmail-default-smtp-server "mysmtpserver")
(setq smtpmail-local-domain nil)
(setq smtpmail-debug-info t)
(setq smtpmail-auth-login-username "myname")
(setq smtpmail-auth-credentials '(("mysmtpserver" 25 "mylogin" nil)))
(load-library "smtpmail")


Here is what I am getting:

Any ideas what's going on? Is it that may be smtpmail with 
authentication has not been completely developed yet? Thanks for your 
help in advance.
