Both ways of usage are common and legitimate, so I would not call it a
coincidence. See

Thanks Wolfgang and Wietse for your explanations!
So it is just a coincidence that the MAIL FROM and From: match for web.de?
Nothing wrong/fishy with the way GMX is using it?
Where would I filter the actual From: of the header? In Postfix or Dovecot?
I found header_checks, but maybe
From: Peter Marius pe...@web.de
To: postfix-users@postfix.org

The From: header has your address, but the MAIL FROM address is
owner-postfix-us...@postfix.org, i.e. the mailing list adminstrator.
This is good
