Problems with Plesk qmail.

[raulica]

The problem I have with qmail is someone is sending SPAM using my server. My queue gets full! I couldn't find how the guy sends spam, and I am sure my customers aren't sending because I knew if someone was sending.

On dnsreport.com I receive the following warning:

WARNING: One or more of your mailservers appears to be an open relay. If so, this means that you are allowing spammers to freely use the mailserver to send out spam! It is possible that your mailserver accepts all E-mail and later bounces it, or accepts the relay attempt and then deletes the E-mail, but this is not common.
WARNING: mail.future-shells.org appears to be an open relay: 250 ok

I guess it is something related with relay ? can you please tell me how to fix it?

Here is a email header:
