Yes, as I indicated: > I have tried to raise this with the owners of various > of the php lists to the "-owners" addresses. [Looking back i see that I sent to the -internals and -db owners, but not the -general owners. Nothing has been done on those and I suspect they will change/update their mailing list software as a common effort for all the lists.] Since the probes don't get rejected I haven't gotten kicked off the php lists, yet. This is an issue that anyone who runs a mailing list should be aware of by now. Yahoo has had their DMARC setting at "reject" for more than a year. I have heard that gmail is enforcing DMARC (I haven't had a chance to confirm this), Yahoo does and other major providers are starting to too, so increasingly list mail will bounce unless the list owners update their software.
