Hello,

I setup ZCS 8.0 Open source edition on Ubuntu 12.04LTS. My requirement is to allow users to send mails to only few domains and blacklist all other domains. We have some specific group of users who need to send mails to specific domains. For example 'Group A' have to send mails to only 'example.com' and 'Group B' have to send mails to 'xyz.com'. Also both these groups have to send mails to 'abc.com'. How do I achieve this with ZCS? Please help me out.
