It is not difficult to detect addresses that never respond.. you send them a link to a page protected by captcha, if they don't clic or fails the captcha then the email is unsupervisioned. They do something similar to "unlist"..
Please note that I wrote: > Maybe there should be a dnsbl for domains /dev/nulling postmaster@ > address and not only for the one not accepting postmaster/abuse > recipient ;-) And you answered that rfc-clueless was an already existing dnsbl for that: I gave them a try but they failed, so I posted the "result". The fact is that they list my "app.mailvox.it" domain because "mailvox.it" shares an MX with "Gmail" (when postmaster@ both domains works and is read) and gmail does not accept email to "postmaster" (with no domain specification) but they don't list alice.it that is dev-nulling postmaster. Pretending that this is for the "RFC" good sounds like a joke, to me, but they host the list, so they have the right to write the rules (I can simply explain people why I suggest to not use that list). So I still hope someone will make a list for domains that dev/null email to postmaster@domain because rfc-clueless "POSTMASTER" list, unfortunately, doesn't do that.
