Which is the accepted format of the HashCash header?
Which is the SpamAssasin accepted default format of the HashCash header?
Im talking about the rules:
Rules/HASHCASH_20 through Rules/HASHCASH_25 and Rules/HASHCASH_HIGH and
Rules/HASHCASH_2SPEND?
What I have understand, these rules are enabled in a default Spamassassin
installation, but despite me of including a X-Hashcash: header in all my
outgoing mails, the rule isn't triggered.
Have tested with multiple third-party SpamAssassin installations.
Im using the v1 format, described here:
http://hashcash.org/draft-hashcash.txt
Do the receiver server need a hashcash verifying program installed for
hashcash to be enabled? (Can't SpamAssassin verify hashcash's itself?)
Best regards, Sebastian Nielsen

...wait, it *is* listed in init.pre, so it looks like it *is* enabled by
default - my bad.

They are based on the hashcash plugin. If the hashcash plugin is not
enabled, they will not be executed. I don't believe it is enabled by
default - look in your v340.pre (et al) file in your config directory.

No, but the plugin does need to be enabled.
I suspect that hashcash never got enough traction for it to be enabled by
default in SA. I doubt many sites will be performing hashcash checks.

Take a look at the documentation
http://spamassassin.apache.org/full/3.4.x/doc/Mail_SpamAssassin_Plugin_Hashcash.html
You need to set "hashcash_accept".
Given that it doesn't work by default, I suspect it's a complete waste
of time.
