This is one of the dumbest responses to spam that I have seen: SBC has begun blocking port 25 for all DSL customers with dynamic IPs. The assumption, I guess, is that this (gigantic) group of people is likely to be using a third party SMTP server to send out SPAM. SBC provides an opt-out feature, but who knows how long that will take. Their grand solutions are basically for you to get your service provider to switch to authenticated e-mail on port 587 or use a VPN. When was the last time any of us had that kind of leverage with our providers? And better yet, why should our providers be forced to switch as a result of SBC's draconian move?
I am as annoyed about spam as the next person, but I just don't think it makes sense to implement these unilateral measures. 99% of the people who now have port 25 blocked are not spammers. There must be a way to identify the 1% who are in order to avoid this hassle for the rest. Sheesh.
Or, I suppose, we could just get on with it on IPv6 and make dynamic IPs a thing of the past.
