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

Re: blocked web site

Hello @ascouter 

 

I am able to access this site using AT&T's wired and wireless networks, so AT&T is not blocking it. Are you using the same computer at home and when you're away? Try clearing your browser's cache and cookies. Are you getting an error message on the site?

 

Thanks,

Dmitriy

Re: blocked web site

I called the Princess Cruise Customer service dept and they have a notice for ATT internet customers saying that
the DMS code of the IP address needs to be corrected in order to get on their sight. This issue is highly localized and does not affect ALL ATT customers; ie my son who lives 20miles from me and has ATT service has no trouble getting on the site. I can use my laptop at his place or at the library and get on this site. It is only blocking me at my house. The router has already been replaced and I have 3 computers using 23 different browsers and no luck form my house.

Re: We are becoming victims of ATNT WEBSITE BLOCKING

i switched my hosting provider, my point is 000webhost and hostinger.in are some of the largest free and popular hosting sites on the internet. Before fcc had its net nutrality rulings isps didnt even have the power to block websites. Users must beware that when they use free hosting services they may be a victim of isp censoring due to the security risk of 1 person hosting a website on the server. This makes us victims of injustice. 

Either way iam recomending my clients that wish to use free hosting services to stay away from atnt. 


There is a reason other isps have not labeled these free hosting services security risks, is atnt unable to provide security and access to the entire web?  

This would be a great selling point to other isps, as soon we will see isps advertising uncensored access to the web. 

Just like organic food the freemarket will dictate the trends

Re: blocked by sbc:blacklist.mailrelay.att.net. DNSRBL: Blocked for abuse

Hello, we've been trying unsuccessfully to get "unblocked" by AT&T for OVER A YEAR, using the online tool to report the issue through the administrator portal.  Is there a chance I can get a real person to review this and help?  If there's more work to be done on our side, we're willing.  We checked our blacklist and spam statuses as directed and we're clear (example: http://ipremoval.sms.symantec.com/lookup/).  

 

Here's the actual block message below.  I can be reached at

Re: Cannot get IP removed from block list

We have the exact same problem.  I even sent a message to the link provided in this post, but our domain continues to be blocked.  This is costing us business and the worst part is costing our customers business.  Please help!!!  MXtools and any other RBL lists show our domain as safe!

Thanks

I am trying to assist a client. Can you tell me how I can get them off this blacklist?

Ip blocked by at&t

Hi Team,

 

For the last couple of months our organizations IP has been blacklisted and everytime we try to send out an email we get the NDR with the below message:

 

521-82.196.43.54 blocked by sbc:blacklist.mailrelay.att.net.\r\n521 dnsrbl: blocked for abuse. see http://att.net/blocks

 

Have logged serveral cases so far by accessing the link http://att.net/blocks , and i guess no one is monitoring it. A few minutes back luckily picked up a working link from the very forum and entered the required information to have the blacklist removed.

 

As the exchange admin gently request that this be looked into at the earliest as several of our users are unable to perform their business critical duties by not being able to send emails to their at&t counterparts.

 

Thanks and Regards,

Ramann

Re: blocked web site

ATT send out a firmware update that some of their gateways did not respond to. A tech had to come out and manually enter data for the gateway to be updated. NOW the site comes up with no issuse.

Re: blacklist removal assistance

I don't understand your answer.  No other email comercial emails systems are bouncing our messages.  Not google, yahoo, live, mail, icloud, etc.Just att.net and its subsididaries.  I have confirmed on multiple occasions with my hosting company that all of our settings and dns entries are correct.  

 

Pleaes elaborate on what issue AT&T is seeing that is triggering your systems to block email from spacegrant.net.

Re: blocked by sbc:blacklist.mailrelay.att.net. DNSRBL: Blocked for abuse

Seriously, who do we need to talk to to get off the AT&T block lists, you are doing your customers a disservice by not allowing them to get legit emails and not allowing other providers to send to your network.

The system that is in place doesn't work, and I'm left trying to answer the questions of "why doesn't your service work" when, in all cases save sending to AT&T, it does work.

 

All of our DNS records are correct, we have reverse, SPF, domainkey records.
