If I am overseas or just connected to a different ISP I still want to be able to use my regular ISP based (eg paradise) email address, even though I am restricted to using the foreign ISP's smtp server. In that case I am neither spamming nor address spoofing, merely using email as the RFC intends me to be able to. -- Nick Rout
