Question

我创建了一个简单的联系表单...当我点击发送按钮时，我将信息提交给我

这是我在本地服务器上运行代码的问题。但它没有运行在实时服务器上（Godaddy服务器）它提供了例外

以下是代码：

Imports System.IO
Imports System.Net.Mail
Partial Class Contact_Form_Demo
Inherits System.Web.UI.UserControl

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim fileName As String = Server.MapPath("~/App_Data/ContactForm.txt")
    Dim mailBody As String = File.ReadAllText(fileName)

    mailBody = mailBody.Replace("##Name##", TextBox1.Text)
    mailBody = mailBody.Replace("##Email##", TextBox2.Text)
    mailBody = mailBody.Replace("##HomePhone##", TextBox3.Text)
    mailBody = mailBody.Replace("##BusinessPhone##", TextBox4.Text)
    mailBody = mailBody.Replace("##Comments##", TextBox5.Text)

    Dim mymessage As MailMessage = New MailMessage()
    mymessage.Subject = "Response from web site"
    mymessage.Body = mailBody

    mymessage.From = New MailAddress("Email Here", "Tuhin Bhatt")
    mymessage.To.Add(New MailAddress("My Email Here", "Tuhin Bhatt"))

    Dim mysmtpclient As SmtpClient = New SmtpClient()
    mysmtpclient.Send(mymessage)
End Sub
End Class

这是我在实时服务器上遇到的错误：

Server Error in '/' Application.
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 74.125.95.109:25

Answer 1

您的托管环境不允许您使用Web.config中指定的设置访问SMTP服务器。如果您的web.config文件中没有<mailSettings>部分，则表示您的应用程序正在尝试访问GoDaddy的machine.config文件指定的设置。很可能，您不允许访问该特定服务器和端口。

请在此处查看如何设置MailSettings部分。并为您管理的网站使用SMTP服务器的名称和密码。

Answer 2

Dim mysmtpclient As SmtpClient = New SmtpClient()

除非您出于隐私原因而忽略它，否则您的SmtpClinet（）会遗漏一些声明，即邮件服务器和端口。
