Hi,

I have to configure a laptop with mutt.
I am able to receive emails, imap is working perfectly.
But I am still not able to send any emails.

From the windows 7 side:

serveur smtp: server.domain.ltd
Connexion: STARTTLS port 587
User need to be authentificated to send email

My .muttrc config:

set smtp_url=smtps://$imap_user:$imap_pass@server.domain.tld:587
set use_envelope_from=yes # Pour que postfix ou sendmail ne change pas votre from
set from="user@domain.ltd"
# activate TLS if available on the server
set ssl_starttls="yes"
# always use SSL when connecting to a server
set ssl_force_tls="yes"
set certificate_file="~/.mutt_certificates"

The only logf I have found (from dovecot)

Sep 16 09:17:22 imap-login: Info: Login: user=<user@domain.ltd>, method=PLAIN, rip=ip_portable, lip=ip_server, mpid=20751, TLS, session=<Uc73Ftgf7gDAqAI0>

When sending, at the bottom of my mutt's windows, I have " Authentification (PLAIN) ..." and that's all ....

Any ideas ?

Thx
