Mailmessage.from不按预期工作

Question

在此先感谢您的帮助！

我想要它，所以当A@gmail.com收到电子邮件时，它似乎来自B@gmail.com。我相信这会起作用，但它似乎继续来自A@gmail.com。我试图使用ReplytoList /头，但没有运气，任何帮助将不胜感激。

using (var client = new SmtpClient 
      { 
       Host = "smtp.gmail.com", 
       Port = 587, 
       EnableSsl = true, 
       Credentials = new NetworkCredential("A@gmail.com", "$$$$$"), 
       DeliveryMethod = SmtpDeliveryMethod.Network 
      }) 
      { 
       var mail = new MailMessage(); 
       mail.To.Add(new MailAddress("A@gmail.com")); 
       mail.From = new MailAddress("B@gmail.com"); 
       mail.Subject = String.Format("Request to Contact from {0}", form.CompanyName); 
       mail.Body = form.Message; 
       mail.IsBodyHtml = false; 
       try 
       { 
        client.Send(mail); 
        retValue = "Your Request for Contact was submitted successfully. We will contact you shortly."; 
       } 
       catch (Exception) 
       { 

        throw; 
       }

这是因为你需要在B@gmail.com添加到您的帐户A@gmail.com作为备选电子邮件地址，否则Gmail的SMTP服务器不会让你伪装的电子邮件地址。
