邮件发送程序源代码

在eclipse下新建一个project，将下列代码拷贝过去，把MailKit提到的邮件服务器和邮件接收者改写一下即可试用，很久以前写的，拿来分享一下，不知各位是否有用

 

package mail;

import javax.mail.*;
import javax.mail.internet.*;

/**
 *
 * @author  selectme_2008
 */
public class SMTPAuthenticator extends Authenticator
{
    private PasswordAuthentication password_auth;
    
    public SMTPAuthenticator(String smtp_user, String smtp_password)
    {
        password_auth = new PasswordAuthentication(smtp_user, smtp_password);
    }
    
    public PasswordAuthentication getPasswordAuthentication()
    {
        return password_auth;
    }
}
