I've tried this at some length and header_checks are a doozy in postfix
as every header line is checked, so it's going to match /^Received/ at
some stage and be put into HOLD for MailScanner to process.
You might be able to achieve something useful in header_checks with
if !/^Received: <from the address to relay direct>/
But only if you can guarantee only one Received header will appear,
otherwise any other Received headers will end up sending the email to
the HOLD queue.
Alternatively, you might be able to do something with the FILTER action
in header_checks, putting your filtering rule before the general HOLDing
rule. I'm unsure quite how that will work though, RTM I guess.
