1. MailSenderInfo
package org.fh.util.mail; /*** 说明：发送邮件需要使用的基本信息 * 作者：FH Admin* from：www.fhadmin.org*/
import java.util.Properties;

}
2.MyAuthenticator
package org.fh.util.mail;import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;/*** 说明：发送邮件需要使用的基本信息 * 作者：FH Admin* from：www.fhadmin.org*/
public class MyAuthenticator extends Authenticator{ String userName=null; String password=null; public MyAuthenticator(){ } public MyAuthenticator(String username, String password) { this.userName = username; this.password = password; } protected PasswordAuthentication getPasswordAuthentication(){ return new PasswordAuthentication(userName, password); }
}
