Thanks Gary, this is what I was looking for, I have little knowledge about exchange and is still in the process of learning as I go.
I can get hard 5XX error on my primary domain below (mydomain1.com) and the Sender Filter seems to kick in as expected. However when I try to send a random email to [EMAIL PROTECTED], Exchange simply accepts it. I have been googling for some pointers to this but I have none so far, would you have any idea why this is so? Many thanks CP [EMAIL PROTECTED] ~ # telnet 192.168.10.36 25 Trying 192.168.10.36...
