Tough, they can do if they want to (although they have never done so,
to the best of my knowledge, they just reserve the right to).

You are collecting mail using POP3, I presume. Demon's other method of
mail delivery is SMTP, the original method, where their machines connect
to yours every ten minutes and give you the mail that is waiting for you.

Yes, both delivering mail and probing you.

But to disable SMTP delivery, see https://www.password.uk.demon.net/
