Prevent *Internal* Spoofing in POP3/Exchange Environment?
Posted on 2007-07-30
We have a large, spread-out organization that allows POP into our Exchange environment. However, theoretically anyone with an account on our Exchange server could change their user information to make it look like the emails were coming from someone else - i.e. change their user name and email address to impersonate our president.
Is there any way of securing this?
Thanks in advance!!
