We are starting to get accounts disabled due to the recent Yahoo DMARC policy change.

Some list subscribers will not receive posts originating from Yahoo accounts.

Mailman has new features for this in v2.1.16 but SourceForge is using v2.1.9. Please could we upgrade the mailman software?

The alternative seems to be to make the list anonymous, or ban Yahoo users.

    I'm raising this to our team to investigate further.

    Our team is opting not to upgrade mailman at this time.

    A workaround to the problem is setting the parameter:

    anonymous_list (general): Hide the sender of a message, replacing it with the list address (Removes From, Sender and Reply-To fields)

    The problem is that in this way the sender have to sign his/her mail, but I think is not a big issue, or at least not more than banning all Yahoo (and other IMP) users.

    Just my two cents,
    Regards

    Now this issue become more and more spread. Many mail domains have "reject" value in DMARC policy. Messages authored by users in such domains and sent by SourceForge Mailman are rejected by recipient servers.
