It's always possible that btinternet.com have been doing wild things with
their MX records, but it's more likely that you are suffering from DNS cache
poisoning, quite possibly deliberate. What nameserver version are you using?
Alternatively, maybe there's something unobvious about the "few bounce
messages". Try forcing a delivery attempt for one or more of them with
"exim -v -M [message-id]" and see if it tries 216.102.246.27 again.
