SPF would work just fine if one sets up the SPF properly (i.e.
to allow from certain domains/IP ranges).
The real trick is that most sites as yet do not subscribe to SPF
or its workings.
: Spam often consists of forged mail. Eliminating 'proper' use
: of forging, such as the justification you were given, would
: not eliminate spam, but would force spammers to stop forging.
: Until forging is stopped, the non-technical solutions to spam
: cannot be applied, since the senders are intractably obfuscated.
Indeed; if SPF were suitably applied, the intractable obfuscation
would not match anything in the SPF once PTR/A/hostnames were properly
correlated/corroborated, and hence the spam would be unceremoniously
...in a perfect world.
