Subject: Outbound Email Blocked - False Positive Error 550 (6-1-1-2)

Message:

Hello,

I am experiencing an issue where I cannot send any outbound emails from my BT email account. Even simple, plain-text test messages sent directly from the official BT Webmail page are being blocked by the server.

The block persists across different networks, and I am continually receiving a false-positive bounce-back error. Could a moderator please escalate this to the email postmaster team to reset my account's spam rating and lift the block?

Here are the exact details of the latest bounce message:

Error Message: 550 spam, or phishing or malware. Please check or edit your message and try sending it again.
Sub-code: (6-1-1-2)
Transaction ID: (6A715E200955A9FF)

Thank you for your help.
