askfilter(1)

NAME
askfilter - Active Spam Killer

SYNOPSIS
askfilter [--procmail] [--logfile=logfile] [--loglevel=loglevel] [--home=homedir]

DESCRIPTION
Active Spam Killer (ASK) is a challenge-authentication anti-spam tool that attempts to validate unknown senders before allowing delivery of their message. Validation occurs by means of a challenge reply sent to senders who are not yet known to the system. Messages are kept in a queue pending confirmation until the sender replies to the challenge. Further messages coming from confirmed senders are delivered immediately. ASK expects incoming mails on the standard input and performs delivery directly to the user's mailbox, as specified in the ~.askrc configuration file. If using the --procmail switch, ASK works as a procmail(1) filter, delivering messages to stdout and setting the appropriate return code for procmail. New users should always execute the asksetup(1) bootstrap program to create the initial ~/.ask directory and a template .askrc file.

OPTIONS

--procmail
    In this mode, normal messages will be delivered to stdout and the corresponding exit codes will be used to mark delivery or not. Use this switch when invoking ASK from procmail(1)

--logfile=filename
    Specifies the file to be used for logging.

--loglevel=loglevel
    Specifies the desired logging level. Defaults to 0 (no logging).

--home=homedir
    Use homedir as the user's home directory. This is needed with some MTAs that do not set the HOME environment variable. It is also useful to run several, isolated ASK configurations with a unique user account.

FILES
~/.askrc
    Main configuration file.
~/.ask
    This directory contains the queued files, temporary files and lists.
