The fact is that the majority of dialup address blocks listed in the DUL are involuntary placement there by third parties. If they (or another dialup IP POP provider) _had_ intentionally opted in (I kind of doubt that EarthLink, for example, intentially severed the ability of their customers to send email to AOL on a voluntary basis, what without a relay infrastructure in place at the time), then they are "filtering port 25 at destinations which have opted to check the DUL before accepting the SMTP connection". A tangent: Kind of like all California drivers "opted in" to surrendering their thumbprint to the state, with the possibility that fingerprint whorls, as biometric data, could demonstrate, with the furtherance of the human genome project, that you perhaps have some genetic predisposition for certain diseases. The same way a picture of someone showing a detached left earlobe has been linked to an expression of genes known to be implicated in both Cardio Myopathy and Coronary Artery disease. Given a state-run healthcare system, like medicare, or worse, a private health insurance agency getting acess to biometric data that indicates that you are a high risk is my idea of a nightmare: "Sorry Bob; I see here that you have an abnormality in the Histamine complex on your chromosone 6 which makes you ineligible for this treatment, since statistically you are 99.95% likely to die from an allergic reaction to dust mites before lack of this treatment would kill you".
