OK I see you MX records points to mx1.iserve.net.nz, I assume they provide some sort of Anti-spam service for you then forward your email to you. Setup your firewall to allow only smtp connections from their (mx1.iserve.net.nz) IP subnet. This way port 25 will only respond to your provider and no one can slip in the back door and use you as a relay....alot easier then following Microsoft instructions. Have you public DNS provider setup an "A"record for mail.st-theresas.school.nz
Hi Kutyi,
I think you are taking me to the right direction here i just need more know how. Not exactly sure where is this firewall and settings i need to configure to restrict port 25 to my provider. At the moment I configure all the email to pop provided by iserve until i resolve the problem with our exchange. i think this firewall and restriction is the answer to my problem as you pointed out I just don't where in our system i am going to go.
Thanks,
abel

It sounds like your Exchange server is being used as a relay for spammers. Read this and implement before opening up your server to the internet. http://support.microsoft.c om/kb/3249 58
