Mail::SpamAssassin::PlUusgeirn:C:oHnatsrhicbausthe(d3)PMearil:D:oScpuameAnstsatsisoin::Plugin::Hashcash(3)

NAME

  Mail::SpamAssassin::Plugin::Hashcash - perform hashcash verification tests


SYNOPSIS

    loadplugin	   Mail::SpamAssassin::Plugin::Hashcash

  use_hashcash { 1 | 0 }   (default: 1)
      Whether to use hashcash, if it is available.

  hashcash_accept add@ress.com ...
      Used to specify addresses that we accept HashCash tokens for.  You
      should set it to match all the addresses that you may receive mail at.

      Like whitelist and blacklist entries, the addresses are file-glob-style
      patterns, so "friend@somewhere.com", "*@isp.com", or "*.domain.net"
      will all work.  Specifically, "*" and "?" are allowed, but all other
      metacharacters are not.  Regular expressions are not used for security
      reasons.

      The sequence %u is replaced with the current user's username, which is
      useful for ISPs or multi-user domains.

      Multiple addresses per line, separated by spaces, is OK.	Multiple
      "hashcash_accept" lines is also OK.


~/.spamassassin/hashcash_seen)

  hashcash_doublespend_path /path/to/file   (default:
      Path for HashCash double-spend database.	HashCash tokens are only
      usable once, so their use is tracked in this database to avoid
      providing a loophole.

      By default, each user has their own, in their "~/.spamassassin"
      directory with mode 0700/0600.  Note that once a token is 'spent' it is
      written to this file, and double-spending of a hashcash token makes it
      invalid, so this is not suitable for sharing between multiple users.

  hashcash_doublespend_file_mode	    (default: 0700)
      The file mode bits used for the HashCash double-spend database file.

      Make sure you specify this using the 'x' mode bits set, as it may also
      be used to create directories.  However, if a file is created, the
      resulting file will not have any execute bits set (the umask is set to
      111).
