Spammers react to Y! DMARC policy


It’s probably only a surprise to people who think DMARC is the silver bullet to fixing email problems, but the spammers who were so abusing have moved on… to
In the rush to deploy their DMARC policy, apparently Yahoo forgot they have hundreds of other domains. Domains that are currently not publishing a DMARC policy. Spammers are now using those domains as the 5322.from address in their emails. The mail isn’t coming through any domain, but came through an IP belonging to Sprint PCS.
This is just one example of how spammers have reacted to the brave new world of p=reject policies by mailbox providers. If only the rest of us could react as quickly and as transparently to the problems imposed by these policy declarations. But changing software to cope with the changes in a way that keeps email useful for end users is a challenge. What is the right way to change mailing lists to compensate for these policy declarations? How can we keep bulk email useful for small groups that aren’t necessarily associated with a “brand”?
The conversation surrounding how we minimize the damage to the ecosystem that p=reject policy imposed hasn’t really happened. I think it is a shame and a failure that people can’t even discuss the implications of this policy. Even now that people have done the firefighting to deal with the immediate problems there still doesn’t seem to be the desire to discuss the longer effect of these changes. Just saying “these are challenges” in certain spaces gets the response “just deal with it.” Well, yes, we are trying to deal with it.
I contend that in order to “just deal with it”, we have to define “IT.” We can’t solve a problem if we can’t define the problem we’re trying to solve. Sadly, it seems legitimate mailers are stuck coping with the fallout, while spammers have moved on and are totally unaffected.
How is this really a win?
