If you’re using the SmtpClient class in the System.Net.Mail namespace of the .NET Framework, there’s an easy way to set the properties of the client without having to wire them up in the code manually.
Simply add the following section to your application configuration file and the class will auto-magically wire up the properties at run-time:
<system.net> <mailSettings> <smtp deliveryMethod="Network"> <network enableSsl="true" port="123" host="myhost" defaultCredentials="false" userName="myuser" password="mypassword"/> </smtp> </mailSettings> </system.net>
There are a whole bunch more settings you can edit. See Microsoft’s <mailSettings> Element documentation page for more details.
