This is not a header check, it is access(5) envelope check that prepends
a header. Given the *data* restrictions cotext, this check will only
fire for messages with a single recipient.

Now not recording more recipients in headers is reasonable, since
otherwise you break Bcc confidentiality. This said, if there is just
one recipient, Postfix already records it in the Received header, so
the whole thing is a waste of time.

Yes, stop doing what you are doing, and build something to extract data
from your logs.
