My point is: If my ISP blocks any outgoing port, he is no longer an ISP I will buy service from. Therefore I do not need a 587-Mailserver, as I do not use any ISP with Port 25-Blocking for connecting my sites or users.Here in Belgium, the two biggest end-user (broadband) ISPs block tcp/25. Are you going to tell your users: "sorry, you should have taken another another access isp, take one of the very few ones left that don't block"?
I am in the lucky situation, where I decide, which providers my users get. Nils
