2 more wish list items...
1) if there is a config file(s), and a message is being sent on stdin, a
blacklist would be nice... just in case one winds up on a mailing list of
"special offers" and they use hashcash... of course a blacklist, in this
context, would only mean that the stamp is not accepted (hashcash -c
returns !0)... the message may still be subject to other filtering, but
these messages (in most settings) don't bypass the spam filter.
~/.hashcash/blacklist:
## mailing list thinks there legitimate marketing
^from: *special-offers*
## my crazy uncle who fwd's me bad jokes
^from: *crazy-uncle@xxxxxxx*
whether such a blacklist only looks at headers is debatable... the option
of using headers and/or body would be great, but *probably* overkill.
2) at some point, v1 (or later) will (hopefully) be widely used, and v0
will be a historical footnote. there should be an option (command line
and/or config file) to determine what version stamps are accepted. if a v1
version of hashcash accepts v0 stamps, there's no way to prevent someone
from "getting lucky" with 1-2 extra bits (and who knows what later
versions will improve on?). what version of stamps are accepted should be
determined by the user.
