Example bounces due to Yahoo p=reject

There are a number of different bounces that people are reporting due to Yahoo publishing a DMARC record of p=reject. I decided to put some of those bounces here so confused users could find out what they needed to do.

Comcast

What can you do if you get one of these bounces?

Endusers can do a couple things. For one-to-one mail make sure you’re using the Yahoo outgoing mail servers and that should fix the problem without you having to really make any change. For email to mailing lists you’ll need to switch to an email address at another domain for that mailing list.

If you’re sending mail through an ESP, you’re going to need to change your header-from address to something other than a @yahoo.com address. This is going to break some things, unfortunately, but as long as Yahoo is publishing this record, you’re not going to be able to use Yahoo.com addresses for your commercial mail.

    This is a huge problem for anyone who runs mailing lists with Yahoo subscribers, which is approximately everyone who runs mailing lists.

    I have some analysis and suggestions here:

    Seems there is no other way to kick out users with yahoo.com suscribers (as the local yahoo servers doesnt seem to be affected).
    Our users use their e-mail for login, and of course yahoo.com users won’t receive any mail from our servers (e.g. changing password) from now on.
    We will encourage this users to pick up another mail-account from an other provider and thats it.

    Just to notify that this post can break some rss readers based on rome. There is a strange character just after “Endusers can do a couple things”.
    If you try to open the feed with a notepad++ you can see it.

    Question: I have gotten both the google and the yahoo messages printed above, but it is not from me mailing anything. I have found that certain but not all the blogs I comment to, the comment never reaches the email box of the blogger, so they do not know I commented unless they go through their comments on the blog post itself. Not a huge issue, but if there is a setting they or I could change, I would. I appreciate any help with this, as this is the only place I have found anything close to being a help to my particular situation.

      One thing you can do is to move to a better email provider – anyone other than Yahoo or AOL. Both AOL and Yahoo have made public policy statements that they do not allow their users to use their email addresses anywhere other than through their service. That includes your sending mail through other providers, and your using any sort of mailing list – and using it as part of a comment on some blogs.

      Gmail is one option for a free service that doesn’t have that restriction.

      The blog operator could work around that by modifying their comment notification script such that it doesn’t use the commenters email address in notifications. Unlike things like mailing lists that’s only a minor inconvenience to them on a day-to-day basis, but it would require all the blogs you use modify their comment notification code, which is enough work that it’s probably not going to happen any time soon.
