All Att emails blocked from sendgrid

When someone signs up through our website an email is sent to confirm Thier account through sendgrid. All emails that belong to ATT or bellsouth are getting blocked by the server at ATT and sending me back error messages. I have emailed the account listed in the error and called support and can't get anywhere with getting my address whitelisted so email can be sent to ATT customers. Please help!!

Hi @Antares! We completely understand your concern regarding emails blacked from sendgrid, and would like to help. Let's get the assistance you require.

 

There are several reasons on why you might not be receiving email from a specific user. Please check on the below steps:

 

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:

  1. In the upper right-hand corner, select the Gear, and choose More Settings to access Settings. 
  2. On the Settings menu, in the left-hand column, select Security and Privacy
  3. Under Blocked Addresses in the right-hand window, you can check for any email addresses being blocked. 
  4. Scan the list of blocked addresses for the ID of the account being investigated.
    Heads up: You could've block a whole domain if you do not enter a valid email address. Check all blocked addresses listed.
  5. To remove a blocked address, highlight it and click the trash can icon. 

If no erroneous blocks were found, or no blocked addresses exist, check the filters. You may have created email filters.

  1. In the upper-right corner, select the Gear, and choose More Settings to access Settings. 
  2. On the Settings menu, from the left-hand column, select Filters
  3. Check for any existing filters that may have triggered, causing messages to route to a specified folder. Highlight the filter name to view what the filter is directing the mail to do. You can edit the filter from here.
    • Example 1: You created a filter to route messages with pizzahut.com in the From field to the folder named Trash. 
      • If this is an email you assume is missing, please check the folder for the message(s) in question.
      • If the messages are found, please check filters/folders. You can leave the filters as is, edit, or delete as they see fit.

Also, please try resetting your password as this could help resolving the issue.


Let me know how it goes.

For further assistance we're here to assist you.

ATT,

I don't have the address blocked in sendgrid. I am getting this error on all Att and bellsouth.net domains when sendgrid tries to send to them.

*****@bellsouth.net

2024/05/08 2:20pm

553 5.3.0 alph730 DNSBL:RBL 521< 159.183.224.105 >_is_blocked.For assistance forward this error to abuse_rbl@abuse-att.net

I have forwarded these emails for over a week now to the listed address with no luck.

It seems I need ATT to whitelist my domain?

ATT,

Just double checked...

We have nothing blocked or filterd. These are for confirmation emails to login to the site that are getting blocked. Every domain works out of the thousands of users except bellsouth.net and att.net

Still no response? I've called so many 800 numbers with no help. Can someone at ATT address this?

There are so many posts regarding the same thing.
