postfix Question

[afiore]

Good Morning,

I am in the process of setting up some applications on my web server that require email to be forwarded to my mail server.

My first question is: Is the YaST > Network Services > Mail Transfer Agent a GUI interface for setting up postfix ? Or is it a different services altogether ?

Second, how do I test the service (what ever I end up using) to see if it sends emails out, prior to configuring any of my apps ?

Thank you,

Tony
