NAME
    spamc - client for spamd

SYNOPSIS
    spamc [-c] [-d host] [-f] [-h] [-p port] [-s max_size] [-u username] [-e
    command [args]]

OPTIONS
    -B  Assume input is a single BSMTP-formatted message. In other words,
        spamc will pull out everything between the DATA line and the
        lone-dot line to feed to spamd, and will place the spamd output back
        in the same envelope (thus, any SIZE extension in your BSMTP file
        will cause many problems).

    -c  Just check if the message is spam or not. Set process exitcode to 1
        is message is spam, 0 if not spam or processing failure occurs. Will
        print score/threshold to stdout (as ints) or 0/0 if there was an
        error.

    -d *host*
        Connect to spamd server on given host.

    -e *command* *[args]*
        Instead of writing to stdout, pipe the output to *command*'s
        standard input. Note that there is a very slight chance mail will be
        lost here, because if the fork-and-exec fails there's no place to
        put the mail message...

        Note that this must be the LAST command line option, as everything
        after the -e is taken as arguments to the command (it's like *rxvt*
        or *xterm*).

    -f  Cause spamc to safe-failover if it can't connect to spamd -- what
        this means is that in case spamc fails to connect to spamd, it will
        not return with an exitcode set, it will instead dump the original
        message to stdout, allowing the message to be delivered, albeit
        unscanned for spam. Without this flag, connection failures to spamd
        will cause message delivery failures.

        Even with this flag set however, if spamc connects successfully, and
        then encounters an error at a later stage of communication, it will
        still return an exitcode.

        This now defaults to on, and can't be turned off. This flag is
        accepted though for backwards-compatibility.

    -h  Print this help message and terminate without action

    -p *port*
        Connect to spamd server listening on given port

    -s *max_size*
        Set the maximum message size which will be sent to spamd -- any
        bigger than this threshold and the message will be returned
        unprocessed. Note that the default size is 250k, so if spamc gets
        handed a message bigger than this, it won't be passed to spamd. The
        size is specified in bytes, and if you send it a negative number,
        things are quite likely to break very hard.

    -u *username*
        This argument has been semi-obsoleted. To have spamd use
        per-user-config files, run spamc as the user whose config files
        spamd should load. If you're running spamc as some other user,
        though, (eg. root, mail, nobody, cyrus, etc.) then you can still use
        this flag.

DESCRIPTION
    Spamc is the client half of the spamc/spamd pair. It should be used in
    place of "spamassassin" in scripts to process mail. It will read the
    mail from STDIN, and spool it to its connection to spamd, then read the
    result back and print it to STDOUT. Spamc has extremely low overhead in
    loading, so it should be much faster to load than the whole spamassassin
    program.

    See the README file in the spamd directory of the SpamAssassin
    distribution for more details.
