我正在尝试使用Kinghost SMTP发送电子邮件,但我有以下错误:

system.net.mail.smtpException : failure sending mail

任何想法为什么?

 private bool SendEmail( string sendto, string sendfrom, string subject, string body )
        {
            bool status = false;
            try
            {
                msg.To.Clear();
                clint.Host = "smtp.kinghost.net";
                clint.Port = 25;
                clint.UseDefaultCredentials = false;
                clint.Credentials = smtpCrede;
                clint.EnableSsl = true;
                MailAddress to = new MailAddress(sendto);
                MailAddress from = new MailAddress(sendfrom);
                msg.Subject = subject;
                msg.Body = body;
                msg.From = from;
                msg.To.Add(to);
                clint.Send(msg);
                status = true;
            }
            catch ( Exception ex )
            {
                MessageBox.Show(ex.ToString());
            }
            return status;
        }

您的ISP可能阻止了端口25上的出站连接。

尝试端口587。
