Emails not being received from a specific email account
A couple weeks ago, I stopped receiving emails from my accountant. His emails are being blocked by mx-sbc.mail.am0.yahoodns.net. How do I get his emails to again be received by me?

Hi @MFKallayII,
We understand how important your email account is, and we'd be happy to help with the emails you're unable to receive.
To get started, we'd recommend clearing the cache and cookies from the device you're using. There could be saved data that is interfering with those specific emails not being received.
Also, please confirm with us if you're using an email client such as Outlook or Apple Mail or if you're just using the web browser every time to check your email.
Let us know if this helps.

Clearing the cache and cookies did not help. I usually go to Currently to check emails. Something just changed with getting emails from this particular sender. Here is what he received on one of the emails that he sent:
Delivery has failed to these recipients or groups:

A problem occurred while delivering your message to this email address. Try sending your message again.
The following organization rejected your message: mx-sbc.mail.am0.yahoodns.net.

Hey @MFKallayII, we’re here to walk you through the right path in fixing email issues.
If you’re unable to receive email from a specific account, possibly, the email may be getting blocked hence we recommend you check on AT&T postmaster to get support.
When their support team receives a request with the needed information, requests are evaluated. If granted, the block will be removed within 24 to 48 hours. There are situations when mail interruptions or blocks are in place outside the AT&T domain. In these cases, we will attempt to make contact with the party initiating the block and seek a resolution. If there is no change after 48 hours, please include the current and complete error message that you are receiving in your follow-up email to abuse_rbl@abuse-att.net.
For further assistance, we are always here to help!
Bruce, AT&T Community Specialist

Thanks, Bruce but the link to the postmaster page was no help at all. Do you have any other suggestions on who to contact?

Hi @MFKallayII, thank you writing back to us. Let's get the help you need.
You may have blocked either their email address or domain extensions (for example, com, org, net). Check if you have the Blocked Addresses feature enabled:
Heads up: They could block a whole domain if they do not enter a valid email address. Check all blocked addresses listed.
We recommend that you go through our article on how to block or unblock an email address
Please feel free to reach out to us for further assistance.
Thank you,
Jasmine, AT&T Community Specialist

If emails from your accountant are being blocked by mx-sbc.mail.am0.yahoodns.net, it indicates that there might be an issue with the Yahoo Mail servers. Here are some steps you can take to resolve the problem:
Check Spam Folder: First, check your spam or junk folder to see if the emails are being marked as spam. If so, mark them as "Not Spam" to help train your email provider's filter.
Contact Your Email Provider: If the issue persists, contact your email provider's support. In this case, if you're using Yahoo Mail, report the issue to Yahoo Support. They may be able to provide specific guidance and assistance.
Whitelist Email Address: Add your accountant's email address to your email whitelist. This tells your email provider that you consider this sender safe, and their emails should not be marked as spam.
Accountant's Actions: Ask your accountant to check if their email server's IP or domain is not blacklisted. If it is, they should work on removing it from any blacklists.
Check Email Filters: Review your email filters to ensure that there are no rules set up that might be blocking emails from your accountant.
Email Header Analysis: Examine the email headers of a blocked email. This can provide information on why the email is being flagged. If there's a specific error message, it may give clues on how to resolve the issue.
Remember, the exact steps may vary based on your email provider. If you're unsure about any of these steps, consider reaching out to your email provider's support for specific assistance.

Yahoo and AT&T are aware of this problem. All the above checks have been done or rejected by Yahoo and AT&T. Neither company is putting this issue on a priority track to get resolved. The issue was created by software that they put into use or someone else put into their system and they do not know how to respond to it.

Hey @MFKallayII!
Thank you writing back to us. Let's see if we can get those emails out,
We recommend that you go through troubleshooting steps
The sections Webmail and Features Troubleshooting and POP Vs IMAP settings are the two sections that you should try first to make sure all the settings are correct.
We also recommend that you try out our Troubleshoot and Resolve Tool to make sure that your email is up-to-date. There is an option for Email Setup and Repair.
Let us know if this works.
Thank you,
