Another relatively painless way to set up a mail server on your own box is http://www.iredmail.org. ( + http://z-push.sourceforge.net/soswp/ for ActiveSync push mail) So far I am fairly happy with it.

Does anyone know, if I used z-push for a product, would I be liable for not buying a license from Microsoft, for Exchange ActiveSync? It seems they are fairly litigious with activesync patents.

The protocol is patented [0]. If you want to offer your product in the US (and other places that care about software patents), you need a license.

Also note that Z-Push is AGPLv3 software. Unless you can get it under another license from Zarafa, you have to release your product with an AGPL-compatible license.
