OK, clarifications... You will see bounces on e-mail services other than Yahoo. GMail implements DMARC but it doesn't itself bounce emails that fail DMARC tests. But when Yahoo servers get your e-mail, they will check the DMARC and reject it, because the way EZMLM (and every other e-mail list software) works is by re-writing the headers. You re-write the headers you break the check-sum or some-such baloney.
And there's several negative votes on Google Groups. Fair enough. At this point, it's probably best if we encourage Yahoo 313 subscribers to move to a GMail account, and sit tight while Brian Behlendorf figures stuff out.
