log full of strange smtp send entries

My postfix log has started filling up within a half a day and there seem to be a lot of strange smpt send entries.

I have SMTP authorisation set to allow only regsitered domains to send tyhrough the server.

Here are some of the entries.

Can anyone tell me how to trace where they came from or hwo to stop them please

thanks
