>Your question begins to lead into a discussion of laws and ethics. You should use one of your own servers to route the email. You could, but should not, route your mail through an external server (If they have proper security setup you will be unable to do so, for example Yahoo and Hotmail). If you do find an external server which will allow you to route the mail then you should notify the administrator of that server. I am not sure what the exact laws are on the subject and if it is even legal to route through an external server.

I will agree on your statement that email servers should be protected and routing shouldn't be allowed with some way to track the real sender but there are many anonymous remailer servers available on the internet that are up for the sole purpose of sending anonymous mail. No authentication or even logging of the senders of the email are incorporated into these servers.
