查看此页面以获取如何发送电子邮件的示例。您应该使用类 Transport 来发送电子邮件。
public static void send(String smtpServer, String to, String from
, String subject, String body) throws Exception
{
Properties props = System.getProperties();
// -- Attaching to default Session, or we could start a new one --
props.put("mail.smtp.host", smtpServer);
Session session = Session.getDefaultInstance(props, null);
// -- Create a new message --
Message msg = new MimeMessage(session);
// -- Set the FROM and TO fields --
msg.setFrom(new InternetAddress(from));
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to, false));
// -- We could include CC recipients too --
// if (cc != null)
// msg.setRecipients(Message.RecipientType.CC
// ,InternetAddress.parse(cc, false));
// -- Set the subject and body text --
msg.setSubject(subject);
msg.setText(body);
// -- Set some other header information --
msg.setHeader("X-Mailer", "LOTONtechEmail");
msg.setSentDate(new Date());
// -- Send the message --
Transport.send(msg);
System.out.println("Message sent OK.");
}

检查是否有人阻塞了 25 端口(防火墙、其他应用程序)
身份验证也可能是一个问题,你可以在这里找到一个很好的例子
props.put( "mail.smtp.auth", "true" );
Authenticator auth = new SMTPAuthenticator( "me@sender.net", "mypassword" );
