Good point. I was more wondering about this as an alternative to purely anonymous e-mail in light of one of the reasons why people try to avoid having e-mail tied to them (government having a peek).
There was an article on HN a while back about a server removed from a DC by the feds; that's one risk.
If you have the server at your home sending emails, it will be trivial for law enforcement to figure out where you are and show up at your door with a warrant to sieze your computer.
