Hi Florian,
For which DKIM signing Domains you see issues? And what are your IP-Ranges?
Feel free to answer off list, if you don't want to disclose this information.

You don't need ARC if you are munging the 5322.From, but if you are munging the
5322.From add a strict aligned DKIM signature, this makes it easy to filter and
trust your lists traffic.
If you run multiple lists on the same domain, please do strict alignment
between 5322.From AddrSpec and the
onsider a DKIM Signature with l=0 as not acceptable.
Besides that, what John said...

Hello Andreas,
Citing RFC 3464 Section 2 Paragraph 4: "The From field of the message header of
the DSN SHOULD contain the address of a human who is responsible for
maintaining the mail system at the Reporting MTA site (e.g., Postmaster), so
that a reply to the DSN will reach that person.

Do you try to add a Range? I had problems with the same Error a couple of years
ago, until I figured out that they also look up the Network IP, so for us it
helped to add PTR-RR to 192.168.0.0 with a Domain that also belonged to us...

* Best practice, don't relay information about internal network structure to
the public, so no internal trace header
* you can only "trust" headers that are signed and pass validation
* totally legit to generate mails on the outbound server

Hi Emre,
Some thoughts from me, I imagine a lot of people from the sender community are
lurking on this list, but it seems to me that for most of them the initial
hiccup of new errors from Microsoft because of the switch from the “old”
Hotmail infrastructure to the “new” Office365 one got
something to the table that
helps to clean up a lot of communication problems an ESP normally faces on the
day to day operations.
PS: i will bring the domain alignment issue as topic to the discussion for
adding that as an requirement for the next iteration of the CSA rules...
Kind regards,
Tobi
