发送电子邮件不在本地工作

Question

Sending email works locally but when I upload my code to my server on bigrock it does not work. I get this error.

Error Request for the permission of type 'System.Net.Mail.Smtp Permission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

My code:

mm.Subject = "Nomination Received";
mm.Body = str.ToString();
mm.IsBodyHtml = false;

SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;

NetworkCredential NetworkCred = new NetworkCredential("abc@gmail.com", "password");

smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);

Answer 1

Make sure your Web.Config file has the trust level set to full

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

you must set the following in System.Net.Mail.SmtpClient variable (eg *smtp *):

SmtpClient smtp = new SmtpClient("relay-hosting.secureserver.net", 25);

smtp.EnableSsl = false; // check if your ISP supports SSL
