解决方案
您的From字段不包含有效的电子邮件地址，因此服务器将拒绝它. VB中的代码并不能解决问题:您可能确实需要授权，就像Medhi上次问这个问题时所建议的那样.
看一看:它可能会告诉您您需要做什么. 使用C#发送带有或不带有附件的电子邮件:通用例程. [ ^ ]
Why error is showing At least one of the From or Sender fields is required, and neither was found? But i have given all field.
My code is given below
<%@ Page Language="VB" EnableSessionState="False" EnableViewState="False" Trace="False" Debug="True"%>
<%@ Import Namespace="System.Web.Mail" %>
<script language="VB" runat="server">
Sub Page_Load(Sender as Object, E as EventArgs)
If Page.IsPostBack Then
lblResponse.Text = "Your email has been sent."
End If
End Sub
Sub btn_Click(sender as Object, e as System.EventArgs)
If Request.Form("Email") <> "" Then
Dim objMail As New MailMessage()
objMail.From = "Email"
objMail.To = Request.Form("contact@kamnatrust.com")
objMail.Subject = Request.Form("Subject")
objMail.Body = Request.Form("Message")
objMail.BodyFormat = MailFormat.Text
SmtpMail.SmtpServer = "webmail.kamnatrust.com"
SmtpMail.Send(objMail)
Else
lblResponse.Text = "Please enter an email address."
End If
End Sub
</script>
<html>
<head>
<style>
.main {font-family:Verdana; font-size:12px;}
.title {font-family:Verdana; font-size:18px; font-weight:bold;}

</head>
<body>
<span class="title" align="center">Send email from
an ASP.NET page</span>
<asp:Label class="main" id="lblResponse" runat="server"/> <br>

<form method="POST" name="MainForm" runat="server">

<td class="main"><input type="text" class="main" name="Email" value=""></td>
</tr>
<tr>
<td class="main" align="right">

<td class="main"><input type="text" class="main" name="Subject" value=""></td>
</tr>
<tr>
<td class="main" align="right">

<td class="main"><textarea name="Message" cols="50" rows="8"></textarea></td>
</tr>
<tr>
<td class="main"> </td>
<td class="main"><input type="Submit" id="btnSubmit" önServerClick="btn_Click" value="Send"
runat="server" /></td>
</tr>
</table>
</form>
</body>
</html>
</br></br> 解决方案
Your From field does not contain a valid email address so the server will reject it.Rewriting the same code into VB isn''t going to fix the problem: You probably do need authorisation, as Medhi suggested the last time you asked this question.
Have a look at this: it may show you what you need to do. Sending an Email in C# with or without attachments: generic routine.[^]
