Big news in the world of email deliverability! Yahoo announced a significant change to the routing of AT&T’s mail. Beginning this week, the MX records for AT&T domains will point directly to Yahoo. While Yahoo has been managing much of the email hosting for AT&T for some time, AT&T maintained its own filters at the MX level. With this mail routing change, those filters will roll into Yahoo’s, streamlining the process.
What’s Changing?
Email sent to AT&T users will no longer be routed through a separate gateway and passed to Yahoo; it will now come directly to Yahoo. The transition will be gradual, so don’t expect immediate changes. However, once complete, Yahoo will be the sole gateway for email sent to AT&T users.
What Does This Mail Routing Change Mean for ESPs?
As an ESP, you should:
- Review and merge your AT&T routing configurations with the Yahoo configs that will take over. If you don’t already have MX-level filters for *.yahoodns.net, you’ll need to make adjustments.
- Monitor for bounces after the change to identify any delivery issues.
What Should Senders Do?
- Stay informed about these changes to avoid surprises.
- Monitor your bounces and performance closely to ensure your emails are still reaching AT&T users.
If you encounter delivery issues Yahoo says you should refer to the Yahoo Sender Hub for support.
