We have a nested security group (ABC) that includes a mail distribution group (123). Would like to use this group in the incoming policy to quarantine emails for all the recipients in the organization except the members of ABC group. We want the mails sent to the distribution group (123) should be able to receive emails as per this exception. However, the members of the distribution group (123) should not receive emails as per this policy. How can we achieve this on ESA running on V 15.5.2
