There's no need to create a file.  If you want to do it from
filter_relay/filter_sender/filter_recipient, just do:

    return('ACCEPT_AND_NO_MORE_FILTERING', 'OK');

Once filter_begin has started, that trick no longer works.  Instead
use a global variable:

my $SkipFiltering;

sub filter_begin {
    $SkipFiltering = 0;

    if (some_condition()) {
        $SkipFiltering = 1;
    }
}

sub filter {
    return if $SkipFiltering;
    # Normal filtering here...
}

sub filter_end {
    return if $SkipFiltering;
    # Normal filtering here...
}
