A lot of people want to use inexpensive broadband connections, and use mail servers at their university or company. For whatever reason, the university and company mail admins only support port 25. If the ISP blocks port 25, the university and company mail admins loose their choice and have to spend money to upgrade their mail servers to support port 587 or something else. So there is lots of "cost-shifting." Do a google search for universities and mail hosting providers that aren't supporting port 587 and offer to help them update their mail servers. When you are finished, then you can advocate ISPs block port 25.
With all due respect to Sean and others, could we all please read "block outgoing traffic from your net to other people's port 25" as including "except for users who request the block be removed" at all times? Yes, I realize that it means you have to approach the block slightly differently, and that it's slightly more work and money to do it that way. But it *does*, does it not, fix most of both sides of the problem, if you do it that way? Cheers, -- jra -- Jay R.
