这是一个从java发送电子邮件的小代码。

public static void sendMail(){
    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.host", "mail.domain.tld");
    props.put("mail.smtp.debug", "true");
            Session session = Session.getInstance(props,
      new javax.mail.Authenticator() {
        protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("sender@domain.tdl", "pwd");
        }
      });
    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("sender@domain.tdl"));
        message.setRecipients(Message.RecipientType.TO,
            InternetAddress.parse("receiver@yahoo.fr"));
        message.setSubject("Testing Subject");
        message.setContent("This is a test <b>HOWTO<b>", "text/html; charset=ISO-8859-1");
        Transport.send(message);
        System.out.println("Done");
    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }
}

但是运行它我有这个错误

我不明白错误的原因,因为此代码过去对我有用。 这是我正在使用的罐子:

  • DSN-1.6.0
  • GIMAP-1.6.0
  • IMAP-1.6.0
  • javax.mail-1.6.0
  • javax.mail-API-1.6.0
  • 测井mailhandler-1.6.0
  • mailapi-1.6.0
  • pop3-1.6.0
  • SMTP-1.6.0

@Bill提出修改后,这是我遇到的新错误

  nested exception is:

但如果删除ssl属性,则为新错误

这与jar无关,但更多的是SMTP服务器错误。 你可以尝试使用

telnet mail.domain.tld

并尝试连接到主机。我建议你加一个像

这样的端口
props.put("mail.smtp.port", "portnumber");

您可以尝试标准端口25(不安全)或587(安全)。
