How to configure for smtps protocol

How to configure for smtps protocol

[Rene]

My company is migrating to a secured smtp server.  It now uses the smtps
protocol on port 465 (instead of the regular smtp protocol on port 25)

Although I reconfigured the vm variables (in Emacs 24) accordingly I can't
manage to make use of this new smtps server.

Here is my configuration file :

(setq smtpmail-smtp-server "smtps.company.domain.name")
(setq smtpmail-local-domain "company.domain.name")
(setq smtpmail-smtp-service 465)
(setq smtpmail-auth-credentials (("smtps.company.domain.name" 465 "login" "")))
(setq smtpmail-starttls-credentials nil)

(setq smtpmail-debug-verb t)
(setq smtpmail-debug-info t)

Besides I don't get any error message which leaves me with no clue on how to
debug  this problem.

Any help would be much welcome.

This is an unfortunate confusion.

In the old days, when VM was designed, people knew the difference 
between mail readers and mail senders (even though mail readers always 
provided links to the mail senders in order to reply to messages). 
Nowadays the distinction between mail readers and mail senders is less 
well recognized.

The point here is that VM is a mail reader, not a mail sender.  The VM 
Info manual that you quoted above is talking about the mail reader.  On 
the other hand, Rene is facing issues with the mail sender, in 
particular the smtpmail package, which is part of Gnu Emacs.

The "Emacs SMTP Library" manual, distributed with Gnu Emacs, is in fact 
the best source of information.  The manual says:

`smtpmail-starttls-credentials'
      The variable `smtpmail-starttls-credentials' contains a list of
      tuples with hostname, port, name of file containing client key, and
      name of file containing client certificate.  The processing is
      similar to the previous variable.  The client key and certificate
      may be `nil' if you do not wish to use client authentication.

Rene has set this variable to `nil', meaning he doesn't wish to use 
"client authentication".  Is that the right thing to do?

(Why the protocols people can't write text that mere mortals can 
understand is always a question for me.)

The EmacsWiki page on GnusGmail, 
http://www.emacswiki.org/emacs/GnusGmail, is also a good source of 
information.  If somebody can write a page like this for VM, the VM 
users would be quite grateful!
