        // Set the host smtp address
        Properties props = new Properties();
        props.put("mail.smtp.host", "smtp.mail.yahoo.com");

        // create some properties and get the default Session
        Session session = Session.getDefaultInstance(props, null);

推荐答案

smtp.mail.yahoo.net 是指向多个不同邮件服务器的CNAME。雅虎恰好在今天的邮件服务器上遇到一些问题...

smtp.mail.yahoo.net is a CNAME that points to a number of different mail servers. Yahoo happens to be having some problems with their mail servers today...
