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

I have sent in many requests and emailed to have my IP address from the Blacklist.  I have also filled out several email and forms and NO response.  We are NOT on ANY Blocklists except yours for some reason.

Hello, we are a web and email hosting company. The IP address of our mail server (184.107.41.242) appears to be on your email blacklist. We are very much against spam and use anti-spam software on our servers, as well as checking them regularly for malware. Our IP address has a good reputation, and we are not on any other blacklist, so we would like to request that we be removed from yours so that our users are able to send mail to your servers. Thank you.

Hello again, dmbpunch. Please double check the IP address you're mentioning. the 192.254.xxx.xxx is an internal IP address, native to your home / internal LAN. This is not a WAN facing IP address.


Please private message us back here with your WAN facing IP address.


Thanks,


-AT&T Community Specialist

I'm trying to understand why AT&T is blocking my domain ip.  We don't send spam. 

I mean it's not even allowing our emails to go into the spam box but completely blocking them from delivery. 

 

Why is AT&T attempting to hurt other businesses?  The only thing to do is spend time writing in forums to try to get this resolved with the Big AT&T Company who blocks emails from little companies without any reasons or any given?

 

I don't think AT&T is going to be around much longer, another more company like Sprint will put them out of business.

 

Our email have correct SPF, Domains keys everything ---you name it all configured correctly.

 

I'm going to add a notice on our contact forms and order forms to use another email addres other than AT&T so they can get there mail. I don't like the way AT&T treats smallers companies making them jump through piles of *** just to get there order confirmation emails, shipping confirmations, and business emails etc.

 

I don't see any reason our emails would be block or even go in the spam box.  

 

Please check your computer systems for malfunction or virus AT&T seance your in the computer business you need to have these things working correctly.

 

Thank you

Hello,

 

Same issue here for 159.135.231.109. We send legitimate subscription based bulk mail and follow best practices for subscribing/unsubscribing, double opt-in, DKIM, SPF, etc. This is a new dedicated IP in our pool so it doesn't have the good reputation yet of our others.

 

5.3.0 alph143 DNSBL:ATTRBL 521< 159.135.231.109 >_is_blocked.For assistance forward this email to abuse_rbl@abuse-att.net

 

Thanks,

Nate

Hi AT&T,

 

One of our clients is trying to send an e-mail and is getting blocked by AT&T. I've noticed from checking around the other forum posts that sending through the error messages to the e-mail address advised does not really go anywhere. I have checked MXToolbox and several other site to confirm that our IP addresses are not blacklisted elsewhere. Can you please unblock our IPs so that our client can send their e-mail.

 

Errors received:

 

553 5.3.0 flph401 DNSBL:ATTRBL 521< 113.52.6.217 >_is_blocked.For assistance forward this email to abuse_rbl@abuse-att.net Last delivery attempt: 13/11/2017 6:27:20 AM

 

553 5.3.0 flpd579 DNSBL:ATTRBL 521< 113.52.6.216 >_is_blocked.For assistance forward this email to abuse_rbl@abuse-att.net Last delivery attempt: 16/11/2017 9:07:24 AM

 

Thanks for your help.

I read through external tipps and forum entries here, and the only way to get an IP resolved seems to be a message here.
The spam removal website has been down for a while, at least a couple of months now: http://rbl.att.net/cgi-bin/rbl/block_admin.cgi

 

: host
ff-ip4-mx-vip2.prodigy.net[144.160.159.22] said: 553 5.3.0 flpd578
DNSBL:ATTRBL 521< OUR-IP >_is_blocked.For assistance forward this
email to abuse_rbl@abuse-att.net (in reply to MAIL FROM command)

 

I checked Spamhaus and Symantec, both have no spam information on our IP, neither has a list of other blacklists we regularly check. Please remove our IP from the blacklist filters - I will gladly give you the IP in a private message.
