Server Admin receiving User Mail List Emails

[Graphrix]

A subscriber has setup a mailing list. People are signing up to the list and we are recieving the emails.

I can't seem to find any settings to change to stop this from happening.

We are up to date and running Parallels Plesk Panel 11.5.30 with the Business & Customer package.

Does anyone know a solution to stop the messages going to us and direct them to the subscriber who is running the mail list?

In the message header there appears to be an error of some sort.

Thank you for your assistance.

The school has currently 390 member responding to each other. I have disabled the mail list for a few days until it has sorted it out and then give it another go.

Best Wishes.
