list.sys4.de will accept mail, regardless if has been DKIM signed or not. postfix-lists modify the subject header and they add a list footer. This will break any pre-existing (valid) DKIM signature. But if there's a DKIM signature it will be verified before the modification takes place and the verification result will be stated in an ARC signature list.sys4.de will append as header to any outgoing mail. Additionally any message from postfix.org will be DKIM-signed just before it leaves list.sys4.de. For the moment this will be RSA-SHA256 only. ED25519-SHA256 will likely follow as stable software to do so will become available. p@rick -- [*] sys4 AG https://sys4.de, +49 (89) 30 90 46 64 Schleißheimer Straße 26/MG,80333 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer, Wolfgang Stief Aufsichtsratsvorsitzender: Florian Kirstein
