I am trying to bulk email but all the messages to email addresses with a btinternet account are blocked and the below message is sent.
The response from the remote server was:
554 Message rejected on 2024/10/20 14:47:05 BST, policy (3.2.1.1) ID (670D7DA602B57DE0) - Your message looks like SPAM or has been reported as SPAM
how can this be sorted?
