Hide mail server credentials in source

I have a desktop application that sends e-mail using a remote smtp server. So in the code, I have something like this:

string userName = "Alex";
string pass = "123456";
sendEmail(userName, pass);

Anyone who changes my application will have access to my mail server. I wonder if there are any solutions to protect sensitive data (userName, pass) from reversing? No obfuscation.

Thanks, Alex.

Move your SMTP credentials and other sensitive data to app.config and use section encryption.

Have you tried to confuse the application? Try Dotfuscator Software Services to confuse your code and then see if it can hide / obfuscate your username and password. It is best to use the app.config or web.config file to save your credentials using encryption or a hash.

There is never a good practice for hard credentials in an application.
