在asp.net中的服务器上托管后，从Web应用程序发送邮件时发生错误

Question

I am Sending mail with smtpclient Object. Mail sends locally, but mail sending fails when web application hosted on server(on BigRocks), I have following error occured.

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

        MailMessage mailmsg = new MailMessage();

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

        mailmsg.From = new MailAddress("xxx@gmail.com");
        mailmsg.To.Add(xxx);

            mailmsg.Subject =....
           mailmsg.Body = .....


        }
        mailmsg.IsBodyHtml = true;

        SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
        smtp.EnableSsl = true;
        smtp.Credentials = new System.Net.NetworkCredential("xxx@gmail.com", "xxxx");
        smtp.EnableSsl = true;
        smtp.Send(mailmsg);

Thanks:)

Would you try to add trust level in web.config

<system.web>
 <trust level="Full" />
</system.web>
