Total block by BT BT for all clients - Urgent and BT postmaster not responding

[Oteam]

Hi, over the weekend BT suddenly started blocking our range of IPs for clients. We work with a number of very large established UK businesses who all follow best practices in line with GDPR and have not had any prior issues with BT.

Our IPs are not listed on any blocklists nor have we made any technical changes that may have led to this. These brands have high customer engagement and are receiving complaints about from customers about the emails not being delivered so the mail is wanted. Most of our clients send from dedicated IPs so there is no cross over between them. The types of email being blocked include double-opt in messages and transactional messages such as order confirmations, so this is having a sever impact. 

The bounce messages we are getting are all: 554 Message rejected on 2023/03/20 22:46:59 GMT, policy (3.2.1.1) ID (63D489EA0832CA48) - Your message looks like SPAM or has been reported as SPAM

We have tried contacting the BT postmaster several times since this started but have not had any responce.

This is a BT residential customer to customer forum. Your post does not go to BT. The only BT staff are the forum moderators who do not necessarily read all the posts.

Your best option is to keep contacting the BT Postmaster until you do get a response. They are know not to respond immediately but they will eventually reply to you.

Thanks. I'm posting here mostly in the hope this gets raised to the moderators so they can add it to the list of complaints about the postmaster service (most other postmaster services respond within 24 hours of being contacts if not same day) or knowing that other have posted on here about similar issue in the past if anyone is able to share details about potential causes as there is nothing in the data we get back from BT prior to this that raises any flags. 

Our senders and their practices are already in line with the best practices listed on the postmaster page and have been for years with no issue. So we don't understand what suddenly changed and why they are blocking all our clients.

I have notified the moderators of the forum about your problem. Once they have read this they may be able to help by checking with the Postmaster. They will advise you by posting on this thread.
