Postmaster

Welcome to the Yahoo Mail Postmaster Forum!

This forum is to gather feedback and suggestions from email senders to Yahoo Mail. If you are any organization (a university, government entity, email marketing business, or an Internet service) that sends email to Yahoo users this is the place to voice your ideas.

Be sure to check out http://postmaster.yahoo.com for some common questions and deliverability best practices recommended by Yahoo for senders before posting. Please use this form to contact customer care for specific issues.

We are always looking for ways to improve Yahoo Mail. Working closely with the email sending community is important for us to continue providing the best in class service to Yahoo Mail users.
We look forward to your creative thoughts and a constructive dialogue together.

Best regards,
Yahoo Mail Postmaster Team

The Yahoo product feedback forum now requires a valid Yahoo ID and password to participate.

You are now required to sign-in using your Yahoo email account in order to provide us with feedback and to submit votes and comments to existing ideas. If you do not have a Yahoo ID or the password to your Yahoo ID, please sign-up for a new account.

If you have a valid Yahoo ID and password, follow these steps if you would like to remove your posts, comments, votes, and/or profile from the Yahoo product feedback forum.

How can we improve your Postmaster experience?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  5. New Webmail ignoring ReplyTo header

    I operate a web hosting system and over 1,500 of my users have Yahoo! email addresses.

    Forms on their websites direct enquiries to them. The forms are sent from a single email address (eg info@mydomain.com) but have the enquirer's email address in the ReplyTo header.

    When my client replies to an enquiry, their reply should go to the email address specified in the ReplyTo header, not to my address (info@mydomain.com).

    However, I've recently been receiving their replies instead of the intended recipients. This is only happening when the client is using Yahoo! mail, not any other provider,…

  12. Yahoo servers are following links in messages

    Yahoo servers are following links in messages
    My firm sends emails to yahoo.com clients with embedded html links that permit the recipients to Accept or Decline.

    yahoo.com clients will click one of the hyper links in the email, then our system logs their response as Accept or Decline, and logs the IP Address.

    We are seeing various Yahoo servers (note list below):

    We are periodically, seeing bulk processes of yahoo.com clients emails which are processing both the Accept and Decline client responses, in each email message.

    The yahoo servers are bulk processing these email messages upto 6 weeks after the…

  13. focus

    For the past two weeks I cannot access my email on my desktop running Firefox 53.0.3; despite my prior contacts to Yahoo, no one has taken up my cause. When I hit the link for a new message, I get this error:

    https://my.yahoo.com/ws/v3/mailboxes/@.id==VjJ-Hn38qgJG19f9S2x9C3rRwE9yZtNylZcBx7DkJkUjFY55DzElR2Caxc-HK0I-Fo1-/messages/@.id==AE9UimIAB_myWSbwxAzJcHoFEMk

    telling me the page with the email does not exist! But, I can access the message on my phone. Would someone focus on this please?

  14. Why can't you allow mailing list sending?

    I'm trying to send a work email to a mailing list address: your system classifies that as an SMTP abuse.

    Your service is amateur, pure ****; I will gladly use Gmail for my needs from up to now, and I will give you a VERY bad feedback to friends and colleagues.

  15. Improving Yahoo pages.

    It takes to long to load, and the advertising takes too many pages which makes slower, also it take you somewhere else other than the page they advertise. It needs to improve on this area also the stories need improvement.

  19. Does yahoo support SPF records with Macros as per the RFC? Getting temperror.

    All other mailbox providers support SPF macros, however, emails sent to yahoo are getting: "Received-SPF: temperror (encountered temporary error during SPF processing of domain of example.com)"

    We are using spfproxy.org's service to help us manage many included SPF records. Is this a know issue? SPF passes with all other email providers.
