14 楼 hsjshijiazhuang 2014-03-03
另外再指出，此程序针对于windows vista 以上系统，c盘是拒绝访问的，所以还得在其它盘符下创建附件文件，或者获得访问权限
13 楼 hsjshijiazhuang 2014-03-03
这里面有错误，我修改了，具体修改是：第216行中，if语句中增加（(fileName != null)），第219行的saveFile方法挪到if语句里面。就不会报错了
12 楼 llxiyuel 2014-03-01
大哥，怎么解析邮件正文输出纯文本
11 楼 yiwanxinyuefml 2014-01-26
请教一个问题，不知道其他人有没碰到过：就是用javamail接收的邮件，正文、附件都可以正常接收，但是邮件正文有一些换行符之类的东西，接收到之后写入到一个文件却是一整串没有换行符的字符串？？？
10 楼 amwyyyy 2013-11-29
不错不错
9 楼 spy41s 2013-07-23
中文会乱码。。。
8 楼 tigerwood008 2012-01-07
如果有附件的哈，好像会有内存溢出的问题，这个该怎么解决！
7 楼 fuanyu 2011-10-14
确实比较全 但是我试了 邮件内容部分还是有问题耶 能否再详细解说下哦

4 楼 bsspirit 2010-08-12
这个不错，很有帮助！！
3 楼 DepthJava 2010-04-12
封装的很不错，乱码问题怎么解决的？
2 楼 containsoft 2009-11-23
大哥，问你个问题，邮件收取进来，并保存为文件之后，要在web页面里一条一条的显示出邮件的日期，标题，发件人，点击进去，查看邮件具体内容，这该怎么做呢。能指点指点么。我邮箱[email protected]
1 楼 maweiqiang 2008-06-04
你好啊，你的这个接受邮件我看了，确实写的很不错啊，我们老师也让我们做一个收发邮件，但是收邮件这里我不太明白，麻烦你能把你收邮件的代码包括页面给我看下吗。非常感谢啊，大哥我的邮箱是[email protected]
