It is possible to do depending on the sacrifices you are willing to take: 5321.MailFrom Domain = imp.ch 5322.From Domain = breitband.ch 5322.Sender Domain = imp.ch
If you run with that you can set DKIM Domain to imp.ch and still send with breitband.ch in your From. And alignment should be fine. But you will get the "via" Tag in compatible MUAs...

(Is Gmails DMARC check broken?) Hi Gang Tanks for the various feedback, learning a log :-) I found one issue caused by domain alignment in DMARC. We use two domains: imp.ch (our company) breitband.ch (our service brand) Our Support Case System (RT/3) uses a global configured envelope sender: <supp...@imp.ch> but depending on the Queue, a different Header From: supp...@breitband.ch Did I get this right? This is not possible anymore when a DMARC entry is published? The envelope sender domain and From: domain MUST be aligned and in the case of 'strict' match, be identical and for 'relaxed' match may contain a subdomain? There is now way to have different envelope and from domains? I guess many ESP sending newsletters do the same, put their bounce processor in the envelope from and a customer supplied From: Address into the header. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________ _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
