      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;

      oMailAddress = 
       new System.Net.Mail.MailAddress("[email protected]", "", System.Text.Encoding.UTF8); 
      oMailMessage.To.Add(oMailAddress); 

      // oMailMessage.CC

      System.Net.Mail.SmtpClient oSmtpClient = new System.Net.Mail.SmtpClient("[email protected]", 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;

执行'Response.write（ex）'并发布_complete_错误消息。 –

我有Response.Write（“Error：”+ ex.Message）;在我的代码，这是完全错误心中已经得到了 –

你只写邮件到响应 - 我建议 '的Response.Write（“错误：” + ex.ToString（））;' 得到stacktrace等等，因此更多关于错误的信息 –

其可能你有错误的设置。

请尝试enableSsl =“假”

尝试请而不是主机“mail.Sohasys.com”把SMTP的IP地址在web.config中。

，为什么你提到的Gmail特定端口...如果你用你为什么使用 “mail.Sohasys.com” 使用Gmail的SMTP谷歌，而不是

请在web.config中插入此

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

将enableSsl设置为false。
