Blocked Domain, Email or IP address Questions and Discussion

Hi, I'm the syadmin of an ESP.   For some reason most of our users with ATT email addresses are unable to receive emails from the system.  We've tried numerous times reporting the issue to ATT blocks, however the issue still exists and our users are getting frustrated.  Can you help please?   

 

This is the ATT error message from our email server.  We use Elastic Email as our Email service provider.  They believe you are blocking our domain for some reason, as they have already moved us to another ip. 

 

 

Here's an example of the error we are getting:

 

553 5.3.0 alph154 DNSBL:RBL 521<64.159.65.119 >_is_blocked.For information send an email to abuse_rbl@abuse-att.net

 

This affects most of the IPs in our netblock (64.159.65.0/24) but not all.  

 

 

We've reported this many times now and gotten no reply. It's been over a month.  We've gone through every remediation step listed here:

 

http://rbl.att.net/block_inquiry.html

 

Filled out the form here a number of times:

 

http://rbl.att.net/cgi-bin/rbl/block_admin.cgi

 

We emailed:

 

abuse_rbl@abuse-att.net

 

I tried this form as well:

 

http://rbl.att.net/end_user_request2.html

 

Any help would be much appreciated!

 

Thanks

 

Dan

Hello,

 

I'm the admin for our server.

 

For over a year and after multiple requests for removal sent to the abuse_rbl without response, we are still unable to correspond with our business partners who use ATT or related addresses. We are a small family owned business and only use our email servers for B2B communication with our suppliers; we are in no way spammers and used to able to communicate with these partners years prior to this.   

 

Please unblock our IP 162.144.205.56

We just turned up a new server with IP address 209.212.146.14 and SBC/ATT immediately began blocking email. The IP is new and has the correct reverse dns entry. Please remove it from your block list.

Please unblock 132.148.129.5 and let me know why it is blocked. I use this to host many websites and it is very troublesome not being able to access. Luckily it is only AT&T.  Does this block applies to all AT&T?

 

thanks!

Did you get your ip issue resolved. AT&T is making me really mad. This is just silly.

It is working now, but no response from AT&T on why it got blocked.  Maybe it is the network congestion or someone at At&t fixed the issue form this community or abuse_rbl@abuse-att.net

I am admin for a private server in Idaho and serve some small businesses.  They are all having trouble reaching att customers like at sbcglobal.net.  I have been sending requests into abuse email account asking for it to be unblocked for over a month.  My reverse dns is setup properly and the server has no other spam blacklist strikes on any of the sites.  I have not gotten a reply back like the return email said I should.  Please rectify these issues this is affecting a non-profits online store.

 

Please unblock 67.222.129.86 

 

This would be very much appreciated.

Hi, 

 

I manage a family business, and for the last few years you have block our emails.

Any customer with an att.net, sbcglobal.net, etc email acount cannot get any emails from us. This includes order confirmations and password resets for our website. And when they attempt 3, 4, 5, 6, 12 password resets.... when they call us in the morning they are FURIOUS. Which we've done nothing to be on your list. I've tried your email help for removal but that goes no where.

 

So please UNBLOCK  69.175.94.10

 

This would save us from so many unwarranted angry phone calls.
