        {
            System.Net.Mail.MailMessage oMailMessage = new System.Net.Mail.MailMessage();

            oMailMessage.IsBodyHtml = true;
            oMailMessage.Priority = System.Net.Mail.MailPriority.Normal;
            oMailMessage.DeliveryNotificationOptions = System.Net.Mail.DeliveryNotificationOptions.Never;

            System.Net.Mail.MailAddress oMailAddress = null;

            oMailAddress =
                new System.Net.Mail.MailAddress(txtEmail0.Text, ttxtPhone.Text, System.Text.Encoding.UTF8);

            oMailMessage.From = oMailAddress;
            oMailMessage.Sender = oMailAddress;
            oMailMessage.ReplyTo = oMailAddress;

            oMailAddress =
                new System.Net.Mail.MailAddress("Soha@sohasys.com", "", System.Text.Encoding.UTF8);
            oMailMessage.To.Add(oMailAddress);

            // oMailMessage.CC
            // oMailMessage.Bcc

            oMailMessage.SubjectEncoding = System.Text.Encoding.UTF8;
            oMailMessage.Subject = "(From WebSite)" + " : " + txtUsername.Text;

            oMailMessage.BodyEncoding = System.Text.Encoding.UTF8;
            oMailMessage.Body = txtBody.Text;

            System.Net.Mail.SmtpClient oSmtpClient = new System.Net.Mail.SmtpClient("Soha@sohasys.com", 587);


              oSmtpClient.EnableSsl = true;
            oSmtpClient.Timeout = 100000;

           // oSmtpClient.UseDefaultCredentials = false;

         //  ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };

            oSmtpClient.Send(oMailMessage);
            Label5.Visible = true;
            Label5.Text = "Your Email Send SuccesFully.";

        }
        catch (System.Exception ex)
        {
            Response.Write("Error: " + ex.Message);
        }

    }

}

Answer 1

请在web.config

中插入

system.net>
<mailSettings>
  <smtp deliveryMethod="Network" from="Soha@sohasys.com">
    <!-- Default Port is [25] -->
    <!-- Specific Port for Gmail is [587] NOT!!! [995]-->
    <network defaultCredentials="false" host="mail.Sohasys.com" enableSsl="false" userName="Soha@sohasys.com" password="XXXX" port="587"/>
  </smtp>
</mailSettings>

将enableSsl设置为false。

Answer 2

可能你的设置错误。

请尝试enableSsl =“false”

Answer 3

请尝试请代替主机“mail.Sohasys.com”将smtp的ip地址放入 web.config中。

为什么你提到gmail特定端口...如果你使用gmail smtp为什么使用 “mail.Sohasys.com”改用谷歌

错误：在asp.net中发送邮件失败
