I'm not sure I understand what you are saying. Mailman's (both 2 and 3) DMARC mitigations allow modifying the outgoing message in some or all cases so the From: domain is the list's domain so the message won't be dealt with by the recipient MTA according to the original From: domain's DMARC policy.
See <https://wiki.list.org/DEV/DMARC>;. Also, <https://wiki.list.org/x/17891458> may be of interest.
Thanks you for the links. According to https://wiki.list.org/DEV/DMARC the MM3 list setting "DMARC mitigation action" (which actually say "Replace From: with list address" in Postorius) should change the From: header. This doesn't seem to work if I don't also set "DMARC Mitigate unconditionally" to Yes, but does if I do.
Where do I change defaults for all lists, instead of a per list change in settings/dmarc_mitigations ?
