比较晕的Jmail发信问题?

[hsf20]

本在自已的机器(win2003)上进行测试:
用的是Winwebmail邮件服务器,我用的ASP发信的代码是:

Set jmail = Server.CreateObject("JMAIL.Message")
jmail.silent = true
jmail.logging = true
jmail.Charset = "GB2312"
jmail.ContentType = "text/html"
jmail.AddRecipient "[e-mail]"
jmail.From = "[e-mail]"
JMail.FromName = "发送人"

'jmail.MailServerUserName = "[e-mail]"
'jmail.MailServerPassword = "mail"
'就是上面的两句,如果不注释就发不出去了,但是问题也是,这样的话不管有没有
真实邮箱,都一样的能发信了,这不很晕.
要怎样才能作到必须有真实邮箱才可以发信息??????

jmail.Subject = "测试用的"
jmail.HTMLBody = tesHtml

jmail.Priority = 3
jmail.Send("192.168.1.1")
'response.write(jmail.log)
jmail.Close()


我在我网上的虚拟主机上试过,如果没有:"
jmail.MailServerUserName = "[e-mail]"
jmail.MailServerPassword = "mail"
就是不能发信了.为什么呀?
