As you see above, the ISP expands virtual aliases before their
content filter. I suspect that this is why they lose the original
recipient.

I don't understand how the conversion from catch...@realdomain.com
to us...@realdomain.com is done.
Regardless, the Postfix Received: header does not show the recipient
with multi-recipient mail. So it is not a good indicator of who the
email was addressed to.
> From: "News" <n...@somedomain.com>
> To: us...@realdomain.com
As mentioned, the To: header must not be used - it does not work
for BCC recipients.
For example, this email reply does not have you in the To: header.
If you were to deliver this email based on the To: header then you
would be sending it right back to the postfix-users mailing list.
