Headers of your message include:

Proper mail clients can provide "list links" based on the List- headers,
but few if any actually do.

So take your pick, but my point remains, it still retains:

And I'm nowhere mentioned.  I only appear in the "envelope RCPT TO:<>
RFC821 header", nowhere in the RFC822 header.

It's not rocket science if you have headers available (which even
Outlook can see, although you have to jump through a few hoops to see them).
