Implementing ARC is the best long term solution, but I understand it's hard. @Matus, rewriting From and DKIM is only necessary if you change anything to the mail that would make the original DKIM fail (changing subject or adding a disclaimer in the body). If you don't, then leaving DKIM and header From intact is probably better. What I would rather recommend to change is the envelope MAIL FROM. If you switch it to a @uni-potsdam.de including some SRS magic, that should cover most issues. But then again, ARC is better longer term.
