spamassassindisable - disable spamassassin for all accounts

    Options:
        --force     bypass 5 second sleep
        --quiet     do not provide any output on STDOUT
        --help      display this message and exit
        --undo      re-enable spamassassin for all the users for which this has been disabled by this script

The force and quiet are useful when running this
script as a part of an automated process (e.g. cron).
