//密碼
objMailMessage.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", sendpassword);
//如果沒有上述三行代碼，則出現如下錯誤提示：服務器拒絕了一個或多個收件人地址。服務器響應為: 554 : Client host rejected: Access denied
//SMTP地址
string smtp = "smtp." + From.Substring(From.IndexOf('@') + 1);

//開始發送郵件
try

return "郵件發送成功！";
}
catch (System.Net.Mail.SmtpException ex)
{
return ex.Message;
}
//核心代碼結束
