Answer 1

如果您使用gmail：

，可以试试这个

 MailMessage mail = new MailMessage();
 mail.Subject = "Your Subject";
 mail.From = new MailAddress("senderMailAddress");
 mail.To.Add("ReceiverMailAddress");
 mail.Body = "Hello! your mail content goes here...";
 mail.IsBodyHtml = true;

 SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
 smtp.EnableSsl = true;
 NetworkCredential netCre = new NetworkCredential("SenderMailAddress","SenderPassword" );
 smtp.Credentials = netCre;

 try
  {
   smtp.Send(mail);                
  }
  catch (Exception ex)
  {               
  }

正如您在问题中提到的，在我的本地计算机上正常运行。
这表明问题是您提供的用于发送邮件的凭证。

如果您使用您拥有的域凭据，则无法在服务器上运行。
用户IIS应具有足够的权限来发送邮件。
