E-Commerce Times Talkback

One of the United States' largest ISPs is about to deploy what may be the best line of defense so far in the war against unwanted e-mail. EarthLink plans to introduce anti-spam technology, dubbed challenge-response, that could prevent spammers from flooding the Internet and corporate e-mail systems with billions of automatically generated e-mail messages. If successful, the technology could put a lid on those annoying ads hawking home mortgages, pornography and miracle drugs.
If all mail servers at ISP and corporations would refuse to relay messages with incorrect or forged headers, the spam problem would not be a factor anymore.
Just by refusing messages received from an address not belonging to the domain advertised in the headers, mail servers would block 80% of spam. Most mail servers are successfully blocking mail relaying that way.
So the real question is why these simple solutions aren't deployed to start with ...
So my question is ... how will this affect ecommerce? Most if not all Commerce Players online have scripted emails that are sent out by their systems to deliver Order Confirmations, Shipping Notifications, etc. Are these SPAM blockers making any attempt to help support online business by working with e-Retailers? Or will customers now have their Order Information blocked from them?
No method will be perfect or impenetrable. Despite its possible flaws, I think it is a move in the right direction. If you only get 5 spam mails a day, you won't have much use for this. However, I know a few people that get over 500 a day! I can imagine the inconvenience of the method is well worth it.
What I'd like to know is how -- "It also has a feature to generate additional e-mail addresses to purchase goods online. Many vendors send sales-confirmation notices via e-mail" (from the article) works. Maybe this is their answer to the e-commerce concerns.
Seems to me that this will affect e-commerce significantly. Any company that has an online shopping presence allows customers to opt in to emails, and uses this method to drive online demand. A site w/ thousands of users won't be able to respond to these emails, so all of their emails will go into the "suspect" folder. It seems to me that this isn't the best idea from anyone's standpoint.
