Hi, > when validating DMARC, it use the envelop address, or use from address from > the header? it unfortunately uses the from-header. (If it would use the envelope address, it would not cause that much problems.)
Or in short: DMARC intentionally breaks every mailinglist and every mail-forwarding. So, if a mail-provider uses a strict DMARC-policy, it effectively says: "Our mail-addresses may not be used for mailinglists." The cleanest solution for mailinglists would be to reject mails from such adresses. (Spoofing the From-header by removing the authors address and replacing it by the lists address, and so hiding the original author, could of course also be done, but is not really a good solution.)
