Answer 1

sorry,太着急了,连用户名和密码都贴出来了...
代码本身没有问题,但是运行出现  Warning!请检查邮件服务器的设置是否正确！"
这段代码应该怎么改popMail.Connect("[email protected]", "388180123", "pop.163.com", 110);
前台就是用几个textbox接受数据.

Answer 2

bin里是Interop.jmail.dll会不会是dll的问题 我下的是4.4 是不是专业版不知道...

Answer 3

System.Runtime.InteropServices.COMException (0x8000FFFF): This function is not included in this version of jmail. 在 jmail.POP3Class.Connect(String Username, String Password, String Server, Int32 Port) 在 MailReceive.Button1_Click(Object sender, EventArgs e) sorry

Answer 4

多半是你所说的版本问题，
据说非专业版本的不能这样popMail.Connect()使用

Answer 5

.aspx.cs:行号 31请检查邮件服务器的设置是否正确！

Answer 6

。net不是自己可以发邮件吗
163现在支持pop3发邮件嘛    

Answer 7

你先确认你的帐户能不能支持SMTP和POP...163只有老用户（05前的吧，忘了）和收费用户才能使用SMTP和POP服务...
