Re: It's nice to see someone normal for a change
For a small home setup, you could also consider using your NAS; there are package for things like Synology that will add a mail server, though I've not used them in anger. That will give you more or less point and click configuration.
And certainly, for some people that's all they need. But this is The Register, and if I walked people through a setup with a friendly point and click wizard, I'm pretty sure a lot of you would feel we could have done much more.
