How to enable SSL for SmtpClient in Web.config

Is there a way to set the EnableSSL from the web.config?

I could set this property in code, but that wouldn't work for the Simple Mail Web Event and other classes that uses the default Smtp Server. Any ideas?

Answer

For .NET 3 and earlier: You can't. You have to manage it by hand.

For more information you can see http://robertseder.spaces.live.com/blog/cns!587F478B9240C01E!270.entry.

For .NET 4: You can.

See http://theoldsewingfactory.com/2011/01/06/enable-ssl-in-web-config-for-smtpclient/

<configuration>
    <system.net>
        <mailSettings>
            <smtp deliveryMethod=”network”>
                <network host="localhost"
                         port="25"
                         enableSsl="true"
                         defaultCredentials="true" />
            </smtp>
        </mailSettings>
    </system.net>
</configuration>
