Hello,
I run a small UK ecommerce business (sending domain: nourishpetfood.co.uk) and our transactional emails to btinternet.com addresses are being rejected with the following error:
554 Message rejected on 2026/06/12 11:08:44 BST, policy (3.2.1.1) ID (6A2B92C3001616DB) - Your message looks like SPAM or has been reported as SPAM
Earlier rejection IDs include:
2026/06/10 10:44:08 BST, ID (6A2791E4004FE911)
2026/06/12 11:04:24 BST, ID (6A28E5E000B90A88)
These are genuine transactional emails (subscription renewal confirmations, account creation and password reset emails) that our customers are expecting not bulk or marketing mail.
What makes this unusual is that all but one email template is affected. Our order processing confirmation emails deliver to btinternet.com addresses without any problem, and emails sent manually from the same address also deliver fine. It is only certain automated templates that are rejected which suggests specific message content may have been fingerprinted as spam at some point.
Technical details:
Emails are sent via Google Workspace from our business domain
SPF, DKIM and DMARC all pass (DMARC policy is p=quarantine)
The domain is not listed on any public blacklist (verified via MXToolbox against 70+ lists)
No other email provider is rejecting our mail this only affects btinternet.com recipients
The issue began on 9th June 2026 with no changes to our sending configuration or email templates.
I have emailed [email protected] but not yet received a response, and customers are phoning us to ask whether their orders and account requests have gone through.
Please could a moderator help get this reviewed and any block or content fingerprint removed? I'm happy to provide full message headers and recipient details by private message.
Thank you
