I am checking the excellent news site
www.theregister.co.uk almost every
day. Today I saw this interesting news article:
http://www.theregister.co.uk/2004/07/05/sender_authentication
Now, what a coincidence! This article matches our recent discussion!
The funny thing: It's probably coming sooner that even I expected in my
wildest dreams ;-) Microsoft will also play an important role.
Here is an extract of the article

Sender ID is expected to be relatively simple to deploy, requiring
little ongoing maintenance. In essence, all you need to do is publish
the IP addresses of approved outgoing email MTAs in your domain name
records. When your users send email, the recipient can make sure the
mail is coming from authorized IP addresses by checking the DNS for the
domain in the "From:" field.
