What’s the best entry level stuff to run?
Just running a free and simple relay is probably the easiest way to do it. I would start playing with stirfry if you're interested. You can modify it fairly easy. Like for instance, I'm running a spam filter in front of my free relay. It's taught me a lot about how to combat spam.
Nice. Learn by doing!
I setup a personal relay, very easy
Will have a crack at figuring this out at some point
yes, but that's also not something that everyone can do either.
