一个读取Gmail邮件的简单程序
????? 兄弟我理论性的东西说不出来，不过实际运用咱还是有办法的
前几天由于工作需要，想了解下关于支持ssl的邮件收发，按照以前普通的做法是行不通的，所以就上网东找找，西瞧瞧。发现了个好东西，并且实验成功。
????? 那天本想来javaeye看看有没有人有相关的经验，找了老半天，连个屁也没闻到，我就说我们，我们这些做程序员的不能老是吹吹水，谈谈道理，我们得拿出点实际的东西出来，就想fins一样，我就很佩服他的贡献精神。
????? 不说废话了，看看源代码，大家有空也可以实验下。还真有用java 代码?

上面代码，完全可以封装成一个收取ssl邮件的库
改天有时间整理下关于发邮件的方法 1 楼 easygodg 2007-04-02 这个东西前几天我刚改的可以根据各种配置发送邮件 ：） 2 楼 yexin218 2007-04-02 呵呵，强人，顶一下！ 3 楼 xuygfbi 2007-04-02 试了一下报错
