Network supplied IP addresses with this configuration are not supplied by simple DHCP and will depend on the node you get connected to when you re-boot the modem/router. I have never got the same (public) IP address when re-booting the modem/router.
OK, it they are configured differently to what I am used to. Including the DHCP servers I manage.

The logs supplied make it clear that the BTInternet mail server is accepting the mail for onward transmission so why it isn't getting to its destination will be difficult to locate without access to the servers logs (and someone in BTInternet support who will/can access and interpret them).
I don't see any issues in the logs either. The IP of the client will probably be passed along to the next server, so that could be the issue. Or it could be the containing subnet being blocked. Unfortunately, there doesn't seem to be a error sent back, but, they could be being blocked as well.
