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

Our IP is blacklisted even though we do our work in a legal way

Hello,

 

We're Avatardesk. Registered and located in Houston, TX.

All of our work is good, clean and not spammy. We're not sure why we have been blocked by AT&T for a while. 

Every time we try to email one of our customers that use AT&T emails, we get a bounce back.

 

Our IP addresses:

158.69.158.25

149.56.40.172

 

Could you please check our two IP's and whitelist them?

 

 

 

Thank you!

Re: BLOCKED EMAIL - Urgent request for IP de-listing assistance

I also would like the block removed for our server.  The IP is 67.225.154.4.  Here's the message from our server logs:

We are not an open relay and we do not propagate spam.  I too have tried all the usual methods listed above.

 

Thank you for your help.

Re: Blocked IP help

I have the same problem.  ATT is blocking the emails that we send out on behalf of our customers. We follow CANSPAM and all ATT requirements. 

 

What do I need to put into the email to abuse_rbl@abuse-att.net  to get a response? I've emailed multiple times now and have not heard anything for weeks.

Cannot send Emails to anyone @att.net / Mail server blocked

We have a mail server which has been on the same static IP for several years but recently started to receive a "553 5.3.0 ... DNSBL:ATTRBL 521< IP_x.x.x.x >_is_blocked" error message when sending emails to AT&T email addresses.

Our mail server is not an open relay, and only has a very small number of users. It sounds like folks have received help via this forum on the same issue in the past.

 

How can I get our server's IP unblocked?

Re: Cannot send Emails to anyone @att.net / Mail server blocked

Hi Everyone,

 

Has anyone gotten their IP Address whitelisted successfully?  It seems like we are all requesting to have our IP's removed from their blocklist but AT&T does not consider this matter urgent when in fact it's damaging the business of many of the institutions that we work for.  

 

AT&T has failed to provide us with a formal process where we can initiate this request.  Nor have they responded to our requests.  They ask us to email an email address that nobody ever responds to.  

 

Users of this forum I think we have to take a stronger approach/stance with this issue.  It's ridiculous that we have to sit and wait for something that is affecting our way of doing business.

 

Our company has a SAS product which provides communication services to our clients.  It's very embarrassing when I have to explain to my clients that we can't email any user that has an att.net or sbcglobal.com domain because we are mysteriously blocked by there servers.  Even more frustrating is the fact that I can't give them an ETA on when the matter will be fixed because I can't get anybody at AT&T to answer nor do I have a number that I can reach them to resolve this matter.

 

Can you please provide an update on having IP "50.57.200.36" removed from your blacklist.

 

Regards,

 

Werner
