Have you ever created a sendmail.cf without using M4?
I still believe that sendmail is Alien technology. How else can one explain sendmail.cf? And although I can't say for sure that I created a sendmail.cf from scratch without using the M4 macros, I can say for sure that I've definitely edited/modified/hacked an existing sendmail.cf file which wasn't working as one would expect. I'm also not 100% certain that m4 was even an option for the first sendmail install I did... my first sendmail setup was probably 25 years ago at this point. I guess I can add my $0.02 to this thread since it resurrected: There have been lots and lots of solutions proposed over the years which would have 'solved' spam in one way or another. Micropayments, authentication, encryption, etc. Each had their strengths and weaknesses. But at this point, pretty much every 'new' solution seems to just be a rehash of an old idea, quite possibly because the person proposing the new solution isn't aware of the past history. I do wonder if some of the old suggested solutions might be more viable today, just because of the increase of computing power available. For example, some of the cryptographic signature-based systems might pay to be revisited since cryptography has become relatively inexpensive CPU-wise.
