There have been very opinionated wars on this where one group would say that messaging evolves and people should adopt to changes required to keep DKIM and DMARC in tact whereas others insist new technology must not break old things. Please lets not start a war on this mailing list. DKIM2 has been said to be mailing list safe and maybe that's the way out: wait until it is being used to sign mailing list messages and switch from SPF, DKIM, DMARC to DKIM2 as fast as possible. > Yes, I know, there are ARC signatures too, and yes, I see this > list does support those.

ARC is about to be deprecated (on this list) soon. 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 Aufsichtsratsvorsitzender: Florian Kirstein _______________________________________________ mailop mailing list -- [email protected] To unsubscribe send an email to [email protected]
