First of all your XML seems to be broken:

It must be something like that: 

<configuration>
  <MailList>
    <MailID id="[email protected]" Value="UK" />
    <MailID id="[email protected]" Value="US" />
    <MailID id="[email protected]" Value="CA" />
  </MailList>
</configuration>

This code should do what you want:

        string country = "UK";
        var result =
            XDocument.Load("~/web.config")
                .Element("configuration")
                .Element("MailList")
                .Elements("MailID")
                .First(el => el.Attribute("Value").Value.Equals(country))
                .Attribute("id")
                .Value;

        Console.WriteLine(result);

You could use the appsettings tag in your webconfig like:

<configuration>
<appSettings>
<add key="[email protected]" value="UK" />
<add key="[email protected]" value="US" />
<add key="[email protected]" value="CA" />

And after that you have your class:

public class WebConfigreader
{
    public static string AppSettingsKey(string key)
    {
        if (WebConfigurationManager.AppSettings != null)
        {
            object xSetting = WebConfigurationManager.AppSettings[key];
            if (xSetting != null)
            {
                return (string)xSetting;
            }
        }
        return "";
    }
}

And in your logic you are calling just:

String strUk = WebConfigreader.AppSettingsKey("[email protected]");
