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?
