Answer 1

se si colpisce l'UnknownHostException: smtp.gmail.com, provare a ping smtp.gmail.com e assicurarsi che hai una risposta (in grado di accedere). Spesso, la tua connessione potrebbe bloccarsi dal tuo firewall o proxy. Altrimenti hai bisogno di javaee.jar e mail.jar nel tuo classpath.

Answer 2

Si prega di provare per questa proprietà di posta elettronica. Controlla che la tua posta invii correttamente.

Properties props = new Properties(); 
props.put("mail.smtp.host", "smtp.gmail.com"); 
props.put("mail.smtp.starttls.enable", "true"); 
props.put("mail.smtp.auth", "true"); 
props.put("mail.smtp.port", "587");
