It looks this is an inbound email. It's not sent from your server, but from hotmail.com

Received: from snt0-omc1-s49.snt0.hotmail.com

Look the direction, the email was sent to the user info.., I guess it means info.sto.pl@stoeu.com and it is your user, right?

Use an Outbound Email Security service. This will make sure that your users cannot mis-use your server to send SPAM.

If they target your users with Spam, install a Spam filter (as in James Santiago's post)

If your server is being used to send spam to other users you might be running an open relay.
