Ask HN: How do you get 'your-domain.com' email address, now Google isn't free?

Google has made their Google Apps for business NOT free some time last year.

So I wanted to know what HN'ers are doing to get their own @your-domain.com email addresses for free?

Apart from

* Doing your own mail server * Paying for it (I know I know...)

I heard Microsoft is offering something similar, but is it actually useful?

As a side note, maybe this is a good idea for startups. :)
