While I don't know the situation wrt majordomo, perhaps "ezmlm-idx"
would also work? There is some support for DMARC in that codebase.
https://github.com/bruceg/ezmlm-idx/commit/925870c82d7ffa6c00ce22cc348e27a48e764a09
When Postfix added support for QMQP in July of 2001, it was to
support ezmlm, which at the time was the only list manager that
was scalable enough to support the SecurityFocus lists with IIRC
more than 100k recipients.
Though that would likely require running qmail for final delivery
on the list input side, with ezmlm and Postfix handling output.
