i'm wondering if is possibile to put on hold emails that not have authenticated in Recieved header .

i've tryed with a simple negate operazione with pcre

!/^Received:.*Authenticated*/ HOLD

As documented, header_checks work on one header a time and don't keep any memory of previous header lines. To achieve what you want, you need to use a content_filter.
