if you want to relay mails from mydomain.com for example, you have to set up an smtp and pop server for mydomain.com, connect to the net through any isp and relay through your smarthost. Your isp will only relay mails from the id_they_have_given_you@yourisp.com
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.
