I think what's happening here is that Paul is arguing from a technical
point of view, as to what kind of firewalling an ISP /should/ do, and
whether blocking outgoing connections on the SMTP port holds any valid
technical purpose.  Martijn, on the other hand, is arguing some
political point about how, if Paul doesn't like it, he should take his
business elsewhere or start his own ISP which, quite apart from the
stunning impracticality of counselling every consumer to start his own
phone/car/internet/financial etc. company if he doesn't like what he's
getting now, is also an entirely a different issue.  If Martijn has any
technical arguments to make, I'd like to see them, otherwise I think the
discussion on free market politics belongs elsewhere.
