Ip Unblock Request: Urgent: Request to unblock our email server IP

I write to request you to please unblock our email server IP: 149.72.116.1. We've emailed abuse_rbl@abuse-att.net as well.
As per our email service provider, the IP has been blocked causing emails sent to our users bounce back.
 
We provide training services to businesses and healthcare staff. Most of these emails are interactions between our users with their site administrators. This includes login information, forget password emails, task reminders, completion notifications, and similar automated email exchanges. 
We use Sendgrid as our ESP. Yesterday, we were informed by our ESP that a lot of our emails are bouncing back with the error: 553 5.3.0 flpd576 DNSBL:RBL 521< 149.72.116.1 >_is_blocked.For assistance forward this error to abuse_rbl@abuse-att.net.
Please unblock our IP quickly. This block is affecting a lot of our clients. Many many of their users aren't receiving any messages. This block is hurting a lot of our customers.
If you can please address this issue as quickly as possible. We'll be really grateful.
Thanks,
PR

Hello @PRapurva

 

You should get a response from the abuse_rbl team.  When was this forwarded to them?

Hi Chris, it has been more than 24 hours since we emailed the abuse_rbl address.

It takes like 3-5 business days.

Thank you for sharing this information. Although, I'd want to have it treated as an escalation, if I could [some how.] But, that would be what I want.

I understand that processes need time. Thank you for responding.
