[Mailman-Users] DMARC issues

I hate to say it, but the days of the kinder, gentler internet when
everyone played strictly by the RFCs are passing as operational control
of internet services comes increasingly under the control of fewer,
bigger players who can do as they wish.
This isn't to say that Mailman should break RFCs too, but there are few
options. SPF inherently breaks mailing lists, which is why heretofore
it's been used mostly as an advisory protocol rather than as a
determinant of whether an email gets delivered, or not. I understand
that SPF is one of the components of DMARC protocols.
This is the first I've heard of this issue, but it doesn't surprise me
