Question about the HOLD header check: why use "Received" ?

[Joolee]

I don't know why the Received header is used. I'm using a simple line of
"/./ HOLD" myself.
A better question is why MailScanner still uses this hack to get access to
the E-mail instead of using the normal Postfix API's available.
