sub filter_sender {
  my($sender, $ip, $name, $helo) = @_;
  return('CONTINUE', "OK") if ($ip eq "72.242.108.6");   # no further checking if localhost
  if ($helo =~ /(^|.)granis.net$/i) {
    if ($ip !~ /^72.242.108./) {
          return('REJECT', "Connect rejected - $ip is not granis.net");
    }
  }
  return('CONTINUE', "OK");
}
