用java写一个邮件发送代码

发送的是QQ邮箱

---

public boolean mainto()
{
boolean flag = true;

//建立邮件会话
Properties pro = new Properties();
pro.put("mail.smtp.host","smtp.qq.com");//存储发送邮件的服务器
pro.put("mail.smtp.auth","true"); //氏旅坦通过服务器验证

Session s =Session.getInstance(pro); //根据属性新建一个邮件会话
//s.setDebug(true);

//由邮件会话新建一镇烂个消息对象
MimeMessage message = new MimeMessage(s);

//设置邮件
InternetAddress fromAddr = null;
InternetAddress toAddr = null;

try
{
fromAddr = new InternetAddress(451144426+"@qq.com"); //邮件发送地址
message.setFrom(fromAddr); //设置发送地址

toAddr = new InternetAddress("12345367@qq.com"); //邮件接收地址
message.setRecipient(Message.RecipientType.TO, toAddr); //设置接收地址

message.setSubject(title); //设置邮件标题
message.setText(content); //设置邮件正文
message.setSentDate(new Date()); //设置邮件日期

message.saveChanges(); //保存邮件更改歼桐信息

Transport transport = s.getTransport("smtp");
transport.connect("smtp.qq.com", "451144426", "密码"); //服务器地址，邮箱账号，邮箱密码
transport.sendMessage(message, message.getAllRecipients()); //发送邮件
transport.close();//关闭

}
catch (Exception e)
{
e.printStackTrace();
flag = false;//发送失败
}

return flag;
}

这是一个javaMail的邮件发送代码，需要一个mail.jar
