Hi you all

I'm experiencing a security issue I don't know where to start to ditch.

At the beginning I didn't spend a substantial time configuring the
security measures in my NE installation, so probably I'm not quite
aware on what I need to focus.

Today, I received an email from "myself" (notice semicolons), the email
content was an advertisement what I'm not aware.

My concern is, why this is possible? Somebody or something is passing trough
the MTA and sending emails targeting the account itself.

But that's not all that's up for grabs...what more can be done without my supervision???

Please, give my your measure about this problem

Thanks in advance :=Poko=:
