Hi,
Currently, i have a mail flow rule that blocks AD group A from emailing AD group B.
it works properly with a custom message sent to group A stating the email failed to deliver when group A tries to email group B.
i added users to group A by setting up a group in AD and added these AD users to group A.
However, for users synced from FIM, i am unable to create a group for these FIM users to join, and hence unable to use the mail flow rules.
is there any suggestion on how to solve this?
