What I would like to know is if there is any way that I
could deny access for users trying to access email via cellphones or email
clients outside the company. I can close everything since there are a few
users that need to get emails from outside the company via cell phone of
email clients.
I was thinking if there was a way to lets say create a group
in AD named: "remote-email" that will allow connection and authentication
from any network, any user not in that group will only be able to
authenticate if the source is 192.168.xx.xx/24.
Is this possible?
