Yeah, but if some idiot gets it wrong who gets blacklisted, the customer or
the ISP? The ISP has to protect customers from eachother too. And if it
blocks viruses also, what a bonus.

I'm afraid that if you want such a service, you may have to pay for it. I
don't think you can point to anywhere in your contract where it said that
port 25 should be open. And anything not explicitly mentioned (or implied by
law) in your contract is just a bonus which can be withdrawn at any time.
Vote with your dollars, go elsewhere.

And they'd ask where you got the idea such a service could be expected.

That's true. Even telstra offered that when they changed the plans around.
