Mr. Borenstein recently wrote the following apparently about that: } ... Grocery stores probably have the right to require their } customers to wear formal attire, but if they don't have a good } reason to do it, they're going to drive away customers no matter } what the outcome of any philosophical debates. My expectation is } that ISP's who implement anti-spam measures that are both intrusive } and ineffective are going to drive away customers as long as there's } a better alternative out there, and I'd be inclined to simply let them } do it unless they're in near-monopolistic market positions. The latter } exception is important, however; I'd certainly be upset if my cable } provider did it, because I don't have any good alternatives. I don't mind in the least if Mr. Borenstein has changed his mind but does not wish to say so. I also don't care if he prefers the ancient statement of the old idea offered by Perry Metzger. I will mind if Mr. Borenstein resumes his campaign against the supposed evils of blocking port 25. Such unfounded complaints give aid and comfort spammers and to marketing departments resisting blocking port 25 for customers who aren't competent to use it. Until consumer grade services providers such as Comcast do something to stem the floods of spam they are sending, other organizations will stem their incoming floods with bad tactics such as rejecting mail from IP addresses with reverse DNS names containing "dsl".
