All emails (from my gmail account) I currently send to btinternet addesses are blocked with the message "554 Message rejected for policy reasons (2.1.2.3)". This includes single addressees so I would be surprised if the messages are considered spam. I seem to have somehow been placed on a btinternet blocked senders list.
Several similar streams on BT Community recommend emailing the Postmaster for help. The problem is the Postmaster address is a btinternet address so when I try and email to it , the message gets blocked!
Any help or advice would be appreciated please
