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：
@Bill提出修改后，这是我遇到的新错误

但如果删除ssl属性，则为新错误

谢谢
答案 0 :(得分：0)
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）。
