Kevin,
Thanks for your quick response!
TL;DR:
if you're suggesting that the
"From: Wolfgang Pfeiffer <roto(a)gmx.net>"
header in my future emails to this Fedora list should be replaced with
something along the line of this:
"From: Wolfgang Pfeiffer via <users(a)lists.fedoraproject.org"
my answer is: yes - I'm fine with that.
There's no way for me to force that to happen in the list software.
It will automatically do that if it detects you are using DMARC with a
policy of reject or quarantine, and not if it doesn't detect that. ;(

Yes: one could try this: But the solution in the tl;dr from above might
end the troubles in one fell swoop anyways - so no further action
probably needed then; Provided I understood correctly, so far ..
I have already tried this, so I guess let me know when/if you get the
bounce. ;) (ie, I have unsubscribed the user who I think is forwarding
to
outlook.com).

Again: Please see my tl;dr from above: is this what your suggesting in
this last part? If yes: as I said above: I'm fine with the address
replacement for this list and for my roto(a)gmx.net address ...
I can't force the list to do this. Your domain would need to enable
DMARC and set reject or quarantine for the list software to decide to
set this for you. ;( This needs a DNS entry added to your domain.
