Storing a SMTP property in AppSetting

I'm working against Azure websites where the portal can be used to over-ride values in the web.config's AppSetting and ConnectionString sections. But other sections still require a transform or hard-coding of the web.config. I need to apply the same control over values found at /configuration/system.net/mailSettings/smtp

Ideally, I'd like to store a string in an AppSetting value and then, when the site boots, it parses this string and over-writes the initial contents of my SMTP section with parsed values found in AppSettings.

Big picture objective: eliminate reliance on hard-coded smtp values of the web.config and instead, apply those values from the portal's listing of AppSettings. Possible?

thx

I'm not too familiar with System.Net.Mail, but you can always read and initialize your own config. You can set the following AppSettings in the portal

smtp.host = <hostName>
smtp.port = <port>
smtp.userName = <userName>
smtp.password = <password>
smtp.defaultCredentials = <true | false>

and then have something like that in your code.

public SmtpClient GetSmtpClient()
{
    Func<string, string> config = s => ConfigurationManager.AppSettings[s] ?? System.Environment.GetEnvironmentVariable(s);
    return new SmtpClient
    {
        Host = config("smtp.host"),
        Port = int.Parse(config("smtp.port")), // handle parsing errors
        Credentials = new NetworkCredential(config("smtp.userName"), config("smtp.userName")),
        UseDefaultCredentials = bool.Parse(config("smtp.defaultCredentials")), //handle parsing errors
    };
}

then when debugging locally you can rely on Environment Variables and when deploying to Azure you use the AppSettings.
