mailServer.properties：

[html] view plain copy

1. mail.smtp.host = smtp.ym.163.com  
2.   
3. mail.smtp.auth = true  
4.   
5. mail.sender.username = [e-mail]  
6.   
7. mail.sender.password = xxxxx  
8.   
9. mail.contentPart.type = text/html;charset=UTF-8  

由于javaMail需要一个Properties来注册Session，因此创建一个Properties来写入javaMail所需要的注册信息

mail.smtp.host 发送方的smtp服务器，现在默认的是网易企业邮箱的smtp服务器，可以根据不同的邮箱进行更改。

mail.smtp.auth 向smtp服务器提交认证

mail.sender.username 发送者邮箱

mail.smtp.password 发送者邮箱密码

还需要两个jar包：activation.jar ,mail.jar
