Question

如何在不使用郵件憑證（如使用本地主機的電子郵件ID和密碼）的情況下發送郵件？

Answer 1

只需創建一個名爲 「信箱」 在你的文件夾C：/驅動器，並使用在Web.config文件如下：

<mailSettings> 
    <smtp deliveryMethod='SpecifiedPickupDirectory'> 
     <specifiedPickupDirectory pickupDirectoryLocation="c:\maildrop" /> 
    </smtp> 
</mailSettings>

對於外部無憑證遞送：

<mailSettings> 
    <smtp from="info@mysite.com"> 
     <network host="smtp.myhost.com"/> 
    </smtp> 
</mailsettings>

使用此代碼表示，

protected void btnSubmit_Click(object sender, EventArgs e) 
    { 
    try 
    { 
    MailAddress SendFrom = new MailAddress(txtFrom.Text); 
    MailAddress SendTo = new MailAddress(txtTo.Text); 

    MailMessage MyMessage = new MailMessage(SendFrom, SendTo); 

    MyMessage.Subject = txtSubject.Text; 
    MyMessage.Body = txtBody.Text; 

    Attachment attachFile = new Attachment(txtAttachmentPath.Text); 
    MyMessage.Attachments.Add(attachFile); 

    SmtpClient emailClient = new SmtpClient(txtSMTPServer.Text); 
    emailClient.Send(MyMessage); 

    litStatus.Text = "Message Sent"; 
    } 
    catch (Exception ex) 
    { 
    litStatus.Text=ex.ToString(); 
    } 
    }
