调用方法：

SMTPMail.sent("test");

使用SMTP发信时「0x800ccc6a」

Ying-er — Wed, 25 May 2011 01:44:00 GMT

除了百度上说的那几点外，要注意检查下自己mail的body里是否有不支持的字符。
比如：在C#里换行是"\r\n"而Java里是"\n"
在C#里误用「\n」换行，虽然debug时看到文本的格式是正确的，但是却发信不能，报的就是0x800ccc6a的错误
另外，C#里有个系统的换行方法：System.Environment.NewLine
理论上这个方法应该更权威，更兼容，但是此方法的测试结果跟「\n」是一样的，【挠头】
