This is default mailing list behaviour since the dawn of the Internet.

This is a new behaviour caused by the DMARC project completely ignoring
mailing lists when they created their new nifty feature.

Unfortunately it is not enough to _read_ that document. ;-)
In this case "pick an option" constitutes of upgrading the mail server
machine OS, installing a newer Mailman that has got these options to pick,
configuring a new web server to handle the mailing list archives,
configuring a new mail server for the new Mailan, and re-implementing
the mail list archive address obscurification via .png pictures that
Mailman still has not implemented. And then "pick an option".
While maintaining the real business...
Hopefully this will happen within a month or so.
