Standardised SMTP Configuration for .NET 30 December 2009
One handy feature of .NET that I keep forgetting is that you can set up default SMTP settings in your App.config/Web.config files, without any code. You could even put this in your machine.config, so that every application always has correct SMTP settings by default.
In your (web|app|machine).config file, add the following bit of XML:
<configuration> <system.net> <mailSettings> <smtp deliveryMethod="Network" from="firstname.lastname@example.org"> <network host="mailhost.example.com" port="25" /> </smtp> </mailSettings> </system.net>
You can also add authentication settings to the network element.
This means that in your code, when a new SmtpClient (and MailMessage for that matter) is created, it will be prepopulated with these settings, thus standardising the setup.
