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.

  1. 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?

  3. 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.

  4. 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.

  5. i need assistance with yahoo and there seems to be no available assistance. i cannot contact anyone.

    my brand new account is suspended for no reason. i havent even been able to use it. i can send mail but not receive. there is no help available and that is absolutely ridiculous. why would someone sign up to spend $50 a year when the email service is so bad? perhaps a real account assistance help line would be a good idea. your email sucks!

  6. MONITORING TOOLS by Yahoo

    I suggest Yahoo to build up Postmaster tools where email senders will be able to follow up their domain and IPs reputation. Similar, like it is for other top ISPs - posmaster.mail.ru, postmater.google.com, MS SNDS.

  7. dont require password changes unless customer wants.....

    difficult for older people to even get account

    I am tired of security that is not driven by me

    automated safety is not safe.

    Diversity should not exclude Americans

  8. Unable to receive emails from Capital One.

    address is not blocked, there are no filters, and the emails are not going to spam. They do have the correct address on file. Can someone please look into this?

    thank you.

  10. 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.

  11. Yahoo FBL is not sending out FBL since 2 days ago, please check.

    Since 11th October 2016, many ESP are not receiving FBL from Yahoo. There seems to be a problem with Yahoo FBL.

  13. Help

    Allow people to directly access help via direct email instead of the 'community' BS so questions can actually get answered.

  18. "Blocking" an email/spam no longer works, you have to "show full header" and block the IP address

    "Blocking Spam" doesn't seem to work any longer. I get MORE mail from the ******* Russian Federation, yet Yahoo can't block that? Gimme a BREAK! If they can send it Yahoo should be on their toes to BLOCK that ****. I've started blocking IP addresses, which has worked pretty well, but Yahoo needs better filtering tools for such nonsense.

    And in 2016 these ******* MORONS are still sending SPAM?
