Any ideas please? I am running under windows 10, both have been stable

It's saying that your mail server is on a blacklist that the recipient
organisation has subscribed to.

No, its saying that a machine on his network is on the blacklist, not
the server (which will be a plusnet machine in this case)

Yes, it's starting to look like there is no outgoing server, and that
the mail client is sending out direct. I just hadn't imagined that
happening, since it seems unlikely to be reliable nowadays.

Following the instructions given by the CBL page would be worth doing:
