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

To Whom It is Concerned:

 

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

Hi there at AT&T,

 

Please unblock our IP address. 185.87.102.234

It is an harmless business from France.

Our IP is not /has never been on any of the blacklists world wide. And we are not propagating spams.

Thanks

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.

To whom it may concern,
We (skillroads.com) are resume writing service provider.
We are facing an issue with sending emails to our clients. Many users from @sbcglobal.NET are asking for refunds due to the fact that they do not receive payment confirmation email and forced to leave our service.
The reason our customers can't receive emails from us is that their emails with activation link are blocked by you.
Please UNBLOCK 144.217.112.49

 

Thanks!

Just a heads up people.  I posted here on the 9th.  I also emailed the abuse email account every other day.  Finally, on the 4th attempt to ATT, I finally got an email back from postmaster stating they would clear the block (not the automated email that is sent after you email abuse).  Seems you just need to be persistent with emailing the abuse email with the same email.  BTW send the email to them under a domain that isn't blocked, for instance, I used my alternate business Gmail account.

Hello, I'm the syadmin of an Infotrax. I have had this issue come up for other clients of ours in the past a couple of years and this has been the only way to get email problems fixed. ATT, scbglobal and Bellsouth email addresses are unable to receive emails from the system. 

 

This is the ATT error message from our email server.  

relay=al-ip4-mx-vip2.prodigy.net[144.160.235.144]:25, delay=0.37, delays=0.01/0.01/0.28/0.07, dsn=5.3.0, status=bounced (host al-ip4-mx-vip2.prodigy.net[144.160.235.144] said: 553 5.3.0 alph735 DNSBL:ATTRBL 521< 192.41.55.156 >_is_blocked.For assistance forward this email to abuse_rbl@abuse-att.net (in reply to MAIL FROM command)

 

I found an issue in the spf record for our client where they had a space in the middle of the server name for the include statement. I helped them make the change and now on a couple of different site the spf record look much better and is showing green without an error.  

Can i get 192.41.55.156 unblocked,

 

Any help would be much appreciated!

 

Thanks,
Ryan
