今天学习了一下JavaMail，javamail发送邮件确实是一个比较麻烦的问题。为了以后使用方便，自己写了段代码，打成jar包，以方便以后使用。呵呵
以下三段代码是我的全部代码，朋友们如果想用，直接复制即可。
第一个类：MailSenderInfo.java
01
package com.util.mail;

private String mailServerHost;
10
private String mailServerPort = "25";
11
// 邮件发送者的地址
12
private String fromAddress;
13
// 邮件接收者的地址
14
private String toAddress;
15
// 登陆邮件发送服务器的用户名和密码
16
private String userName;
17
private String password;
18
// 是否需要身份验证
19
private boolean validate = false;
20
// 邮件主题
21
private String subject;
22
// 邮件的文本内容
23
private String content;
24
// 邮件附件的文件名
