I tried to minimize/suppress the email header from all of my email sent to outside world by removing the extra information that is sent with the email by using EMC and then configuring the Transport rules like these:
Apply rule to messages
from users Inside the organization
except with a spam confidence level (SCL) that is greater then or equal to 5
I'd like to know what does this Transport rules perform then ?
when i check from the email that i sent to other user inside my domain and GMail i could see the header from my exc. server name and my internal ip address.
how can i remove them completely to get rid of internal domain spam (spoofed header) ?
