Hi all,
As we've discussed in this thread and others recently,
messages from subscribers @yahoo.com do not reach
subscribers @gmail.com (among others). This is due to an
aggressive policy set by Yahoo which breaks mail sent via
the mailing list.
The mitigation enabled should change the From: address of
the outgoing mail to the list address. This should only
apply to users of @yahoo.com and other domains which set a
similar DMARC policy. Subscribers at other domains should
see no change to the From: address of mail they send to the
list.
I believe that only the email address will be changed, and
not the sender's name, but I am not certain of that yet.
Hopefully this mitigation will work well and provide an
overall improvement to the list. If not, we'll revert it.
Would this change be why I'm suddenly seeing oodles of old messages
showing up on the list? Messages that I've already seen, since I don't
have a problem with messages from yahoo addresses being invisible. I'm
not sure what this will do to any messages I've saved - will they be
deleted when I delete these old messages that are showing up as if they
are new?
