Huh? ISPs need to check for valid senders. They can do this by a) Requiring you to be in an IP block they control b) Using POP before SMTP c) Using SMTP Authentication d) Using TLS AUTH
A properly setup ISP does not care about the sender's email address.
i have an account at your isp - kg@dvb.com. I access my pop box, and then within the next 30 minutes i send spam all over the world from ids like kg@sherlock.com - assuming there is a domain registered and live called sherlock.com, you will relay these mails?
