No, the logs show 5 incoming messages (from [::1]) each to the same 5 recipients. Any bifurcation is upstream. Perhaps a misconfigured content_filter? > I'm just curious about the > message-id=<008b01d10ca4$eb5fd0b0$c21f7210$@de>, this is always the > same, but the postfix ID differ. Any glue? The clue is that 5 messages arrived, so Postfix delivered all 5 messages. I've "collated" the logs below. You need to look at the "Received" headers of one of the messages to determine how it got to "[::1]".
