Use DomainKeys instead of SPF. DomainKeys serves the same purpose, but doesn't share the fundamental brokenness of SPF.
And why not using the existing authentication protocol on outgoing smtp server ? So the sender can use the smtp server of the provider of its email address from any network and SPF can work without any problem.
Did i forget anything ?
