Is there any way to prevent internal users to send Spam to Internet using Astaro?

Is there any way to prevent internal users to send Spam to Internet using Astaro?
Astaro is accepting relay only from mail server, but some infected machines are sending ton of spam to Internet through mail server and Astaro.

The internal machines are using dynamic IP´s.

Thanks in advance.

Best Regards.

    Sandro, what version are you on now - 9.105-9?

    Please show a picture of your 'Anti-Spam' tab including 'Spam detection during SMTP transaction' and 'Spam filter'.  Also, 'Content scan for relayed (outgoing) messages' on the 'Relaying' tab.

    Confirm that there is no Exception for "Antispam checking" for your domain.

    Do you have Sophos Endpoint installed on your clients?  Some other security package?

    Cheers - Bob
