  • How can i block spam in my Ex 2k3

    Hi everyone, i have a problem with spam in my domain. Some people on my organizations is receiving mails with my domain. For example my domain is @dominio.com.pe and an user got a mail from [email protected] (spam from another server), however this mail account [email protected] doesnt exists in my organization. Can anyone know how can i block this spam, maybe in the configurations of the SMTP virtual server, i can select "authenticated users" for send mails.
    Plz help. Thanks.

    (pay close attention to the first non-commercial result...)

    In any case, stopping spoofed email that appears to be sent from your domain is easy, if NO EXTERNAL USERS is supposed to send SMTP mail from outside. In that case, when all users eaither use Outlook or OWA, you can enable the SENDER FILTERING and add your own domain to the blocked domains. You must configure the setting on the Global Settings area of ESM, and after you do that you enable it on the SMTP Vistual Server.
