Hashcash is a denial-of-service counter measure tool. It's main current
|
|
use is to help hashcash users avoid losing email due to content based
|
|
and blacklist based anti-spam systems.
|
|
|
|
The hashcash tool allows you to create hashcash tokens to attach to
|
|
emails you send, and to verify hashcash tokens attached to emails you
|
|
receive. Email senders attach hashcash tokens with the X-Hashcash:
|
|
header. Vendors and authors of anti-spam tools are encouraged to exempt
|
|
mail sent with hashcash from their blacklists and content based
|
|
filtering rules.
