All, Pretty simple question:
We have an internal domain, zimbra.example.org, but it's only used for internal routing of our corporate mail (there's a master delivery map that controls what addresses at example.org route to zimbra.example.org). We have other domains under example.org such as list servers, ticket systems, and the like, many of which have example.org addresses pointing at them. In no case should anything on the outside be directing mail directly to zimbra.example.org, and it is firewalled so only our border MXes can talk to it. Is there a way to reject mail destined to an internal domain (like zimbra.example.org) such that only our internal machines can deliver to it, but that any host on the outside gets an immediate reject notice from our border MXes? -Dan _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
