It's because Yahoo sign their outgoing emails with DMARC, which
basically makes them unsuitable for use with mailing lists (the mailing
list is not authorised to send emails on the user's behalf, which is
essentially what is happening here).

There are messy workarounds for mailing lists, but in the short term I
wouldn't use a Yahoo email address with a mailing list.

Gmail will be making the same change sometime next year, but hopefully
by then ARC will be implemented which will provide a potential fix.
