Quelqu'un saurait-il m'indiquer d'où peut venir le problème ?

Merci d'avance pour votre aide.

Bonjour,

A mon avis, le port n'est pas le bon. Vous devriez vérifier le port utilisé par le serveur SMTP, ainsi que le protocole (TLS?)

Bonjour, essaye d'ajouter çà

Code:

1
2
props.setProperty("mail.smtp.starttls.enable", "true");
props.setProperty("mail.smtp.port", 587);

Voici le code en entier plus les modification que j'ai apporté.

Bonjour,
l'erreur : java.net.SocketException: Permission denied: connect
L'utilisateur n'a pas les droits de connexion au smtp.

en effet, j'ai trouvé la solution. Le probléme est un bug avec java 7, il faut ajouter '-Djava.net.preferIPv4Stack=true' a JVM system property. Merci pour vous.
