谢谢斑竹！
这个类是什么类？用途是什么？怎样建立？
下面是木瓜和流星雨的源码，请您看看，帮忙分析一下：
Set Library To myfll
hPop3=Pop3Create("pop.,"帐号","密码")
If hPop3==""
MessageBox("无法连接服务器")
Return
EndIf
nCount=Pop3AMailList(hPop3,"aMail")
&&邮件个数
If nCount<0
?"无法取得邮件信息"
Pop3Close(hPop3)
Return
EndIf
For x=1 to 2
&&把2改成nCount可以下载每一封邮件
cMailBody=Pop3GetMail(hPop3,aMail[x,1])
&&下载邮件
* StrToFile(cMailBody,"mail"+Transform(x)+".eml")
&&把邮件保存到磁盘
*下面这段代码，使用网友 流星雨 写的解码程序，对邮件进行解码
oMail =
NEWOBJECT('Mail')
oMail.LoadEML(cMailBody)
&&这里解析邮件
