Emails bouncing back

When sending more than 10-15 emails messages at once, they get returned as undeliverable.  If I resend them one by one - they go through.

We're happy to look into this for you, @gvc.

 

What email domain are you using (AT&T, Yahoo, SBCglobal, etc.)?

Have you performed any troubleshooting on your email account? We have a handy guide here in the forums if you need it.

 

We'll be awaiting your response!

Thanks for the quick response.  I am using the att.net domain.  We have all of the settings correct and have done all the troubleshooting.  It previously worked fine but just started doing this.

We are sending emails to our clients that have REQUESTED us to send to them their information about appointments, etc.  We are NOT sending anything mentioned in your reply?  So, how can we resolve this issue.  It is very difficult to proceed and do business using AT&T.  Can you please address our particular problem and yes we definitely need FURTHER ASSISTANCE.  Thank you.

Hey @gvc,

 

The Email bounce back you are receiving will have an error code attached to each message. You will need to Email the postmaster at abuse_rbl@abuse-att.net with the error code to resolve the bounce back errors you are receiving.

If you are running an Email server under port 25. Port 25 is blocked by AT&T due to spam and malware threats. Click here to find out more about AT&T Network Practices.

 

Let us know if this helps.

I have sent the error code previously and still no results.  Can you tell me how this can finally be resolved?  This is the error code below:

 

Your message did not reach some or all of the intended recipients.

 

      Subject:     Appointment Reminder

      Sent:  07/02/2020 10:22 AM

 

The following recipient(s) cannot be reached:

 

      'EMAIL ADDRESSES HERE' on 07/02/2020 10:22 AM

 

            554 6.6.0 Error sending message for delivery.

 

I did send it to the abuse_rbl@abuse-att.net email but it still is not resolved.  

 

Thank you for any further assistance you may provide.
