在升级 1.8.0\_151 后，mail 发送电子邮件的时候出现错误，不能连接服务器等提示。

这个提示很笼统，当你打开 Mail 的 debug 后，你会发现其实是版本不兼容的问题。

如果你还在使用 mail 1.4 的话，你需要升级到 1.5 了。

错误的信息大致如下：

`DEBUG: JavaMail version 1.4ea

需要使用最新的 mail 版本：

` <dependency>
			<groupId>javax.mail</groupId>
			<artifactId>mail</artifactId>
			<version>1.5.0-b01</version>
		</dependency>`

就可以解决这个问题了。
