Impression based on what? There is a 'hold' queue, but no such
thing as a 'hold' transport.
You can destine messages to the 'hold' queue with an action in an
access table, header_checks, body_chgecks, or Milter quarantine
action.

Then you made a mistake, see below.

FYI, smtpd can only receive email.

You are ignoring Postfix warnings at your peril.
"access table %s: with smtpd_proxy_filter specified, action %s is
unavailable",
You need to 'hold' after the smtpd_proxy_filter.
