SIMS spam used

[Adri� Vidal romero]

Hello got my SIMS mailserver up and running for some time, and since a few days ago i find a lot of messages sent without authoritation.
My SIMS machine runs as POP server and SMTP only for internal accounts, relay is not permited. Someone can help me stopping this spammer using my server.
