Mark and Andy,
I wrote my own super fast, pretty tiny list manager and mailer -- it
includes a web interface, archiving mechanism, ...
I noticed that for yahoo (and aol) email address I too have to rewrite
the From line (though by default I do not). It is configurable on a
domain by domain basis. This seems to work for yahoo mail delivery -
but sucks.
I appears that just as delivery settles down, someone - gmail, yahoo,
... makes a change that I need to chase down.

For years, Yahoo has rejected mailing list email with From lines from
domains with a DMARC record with p=reject or p=quarantine. We
identified a Yahoo policy change in early November, affecting
handling of mailing list email from domains with a DMARC record of
p=none. Previously, they would accept mailing list emails sent from
these domains without having to re-write the From line. Since the
policy change, they have started bouncing those messages.
Thanks Mark, good to know.
Our policy had been to not re-write the From lines of emails sent
from p=none domains. In light of this change and to clear up other
confusion, we now re-write From lines from domains that have any
DMARC record. Which, alas, ends up being most of our list traffic.
Interesting. It does seem a shame to do as such, given that when
operating within published standards means one shouldn't have to, but
I guess when you want to ensure email is delivered...
