Re: [mailop] Yahoo DMARC changes

Are you taking that approach because the workaround is less than ideal?  
Otherwise the current “workaround” could be the new standard.

That's interesting. From an ESP's prospective, deciding to use a different
domain in the from address is simply not an acceptable option. That being
said, I wish we had a good way to tell senders that they are heading for
trouble. You would be surprised how many senders don't know that there is a
part of their infrastructure that is using these domains in their from
address.

[mailop] Yahoo DMARC changes

2016-03-22 Thread Steve Atkins 
Yahoo recently posted elsewhere[1] about upcoming changes with their DMARC 
usage, and I thought mailop might be interested.

As of next Monday y7mail.com and a huge list of international yahoo.* domains 
will be switching to DMARC p=reject, matching yahoo.com's configuration.

So if you've been doing anything special with forwarders or mailing lists for 
yahoo.com it's probably a good idea to do it for their other domains too in the 
next few days.

There's an easily copy-and-pasteable list of the affected domains at 
https://wordtothewise.com/2016/03/more-yahoo-domains-get-dmarcd/

Cheers,
  Steve

We have convinced some of the Powers That Be that we should find another 
solution, and there is an open-ness to change on this behavior. Not gonna be 
this week or this month ... who can say for sure. But noise is being made about 
it.

Aloha,

This has been going on since like early 2000's, they couldnt fix 
cleanfeed then, so why you think or expect they can now is beyond me :)

Reply to the ticket and request an escalation, set forth your case ... and wait.
A human will respond, even though it's with boilerplate.

Hi,

I did this for on of my IP, but the machine thinks it should be kept
blocked.
But, the /24 just appears on the Internet (was not even routed some
moths ago) and the mails are delivered if we use an IP from another
range.

What should we do in that case?
