gnus and smtp auth

[Samir Saidani <saidani@info.unicaen.fr>]

Hi all !

I'm trying to get gnus sending mail through smtp auth, but after
several hours, I'm definitely unsuccessful...

So here is the situation : I've got a laptop with a sarge debian
installed, and using gnus 5.10.7 and emacs 21.4.1, with the latest cvs
smtpmail and starttls files (byte-compiled).

I managed to send mail through smtpmail and without authentification
with no problems, and I can send mails through smtpmail with
authentification using gmail (I tried the .gnus here :
http://web.phys.ntnu.no/~terjeros/gnus-gmail/)

I also managed to send mail to smtp.xxx.com in few minutes (argh) using
mozilla mail, with the following settings : 
outgoing smtp : smtp.xxx.fr 
port 465 
use secure connection : ssl (the other choices don't work).

When I replace the .gnus configuration (from terjeros) with the right
settings, it hangs and there is nothing in smtp debug.

But I find a difference between smtp.gmail and smtp.xxx.com :

when I do a telnet :

gmail
Trying 64.233.185.109...
Connected to smtp.gmail.com.
Escape character is '^]'.
220 mx.gmail.com ESMTP d16sm1394590wra


smtp.xxx.com
Trying 2001:660:7101::6...
Trying xxx.xxx.xxx.xx...
Connected to smtp.xxx.com.
Escape character is '^]'.


and with
gnutls-cli  smtp.xxx.com -p 465

Resolving 'smtp.xxx.com'...
Connecting to 'x.x.x.x:465'...

So I tried different possibilities to get a .gnus.el working but now,
I'm stuck !

Help ?

Thanks !
