我使用此代碼發送郵件。 但這些郵件到達垃圾郵件文件夾。郵件到達垃圾郵件
MailMessage message = new MailMessage();
message.From = new MailAddress(ConfigurationSettings.AppSettings["From"]);
message.To.Add(new MailAddress(ConfigurationSettings.AppSettings["To"]));
message.Subject = ConfigurationSettings.AppSettings["Title"];
message.Body = ConfigurationSettings.AppSettings["Body"];
SmtpClient client = new SmtpClient();
client.Send(message);
爲什麼? 我該怎麼辦?
感謝
