Outbound Spam
Hello all.
Question regarding outbound Spam. At the moment i have it delivering the suspect mail to be, but the ultimate question is, how do i find the origin of the spam. if the user is on Outlook, then we have no Sending IP we can find to identify the source.
So, is there anyway i can find the source of the spam ?
Many thanks
