Been a long time since I used Postfix, sorry for this basic question. I have a Postfix server used internally by servers in the network to send out mail. Itself relays all mail to an upstream server.
How can I reject mail from given clients (list of IPs), but only if destined for domains other than a given list of domains. am confused by the fact that for my Postfix, all mail is "relay" mail... and no domains are defined as "local"... so I can just say restrict relaying to this list of clients. Thanks a lot, Mohamed.
