I understand that given everyone uses gmail, hotmail or mail provided by some multinational hosting service they assume mail coming from residential connections cannot be other thing but spam sent from hacked machines. But someone paying for a static IP in a residential connection is the opposite case. When you have to deal with thousands of users you resort to any trick you find on the Internet and start to blindly blacklist all; this is a big servers problem. And the more users you have to deal with the worse. On the contrary, from my part, I have just a pair of personal addresses, so it's not a big deal for me to audit my server and use more sane, less harmful and, overall, more effective measures to filter spam and to prevent spam be sent from my machine. And I think this is the direction everyone should point to instead of resting day after day more and more on big companies for everything. In general, everyone should tend to decentralize instead of monopolize. The real problem is the passive attitude most people assume in the use of the Internet (and life in general but I don't want to bore you with cheap philosophy. :-))
> > Regards, Thank you for your advice. +1, way more spam comes from universities and enterprise machines than residential static ips with PTR records. It is not your error to fix. BTW Microsoft have their own SPF sign up thing but if I recall it was too much hastle and maybe pay for. Keep ignoring those that suggest using your ISP, why would you send *all* your mail through a likely untrustworthy mail system. Just accept that hotmail users often fish mail out of spam because the big mail systems are crappy.
