Thank you for your replies. I investigate further and found that it was a Postfix error in configuration. Though I don't understand if BATV was truly playing a part in it, the server was rejecting unverified senders, but there wasn't a hash map to indicate verified senders. I have fixed this.
I based my findings from my search for "prvs=" in Google.
