今天无意中看到了JavaMail有这样的协议支持描述:
- Protocol Store or Uses Supports
- Name Transport? SSL? STARTTLS?
- -------------------------------------------------
- imap Store No Yes
- imaps Store Yes N/A
- pop3 Store No Yes
- pop3s Store Yes N/A
- smtp Transport No Yes
- smtps Transport Yes N/A
- public class JavaMailTest1 {
- public static void main(String[] args) throws MessagingException {

- props.setProperty("mail.debug", "true");
- props.setProperty("mail.smtp.auth", "true");
- // 协议名称设置为smtps,会使用SSL
- props.setProperty("mail.transport.protocol", "smtps");
- Session session = Session.getInstance(props);
- Message msg = new MimeMessage(session);
- msg.setText("你好吗?");
- msg.setFrom(new InternetAddress("发件箱地址"));

- transport.connect("smtp.sina.com", "用户名", "密码");
- transport.sendMessage(msg, new Address[] {new InternetAddress("收件箱地址")});
