I want to use postfix at my serverB (fictive ip: 1.2.3.4) and postfix at my serverC (fictive ip: 5.6.7.8) to send all its outgoing mails via my postfix at my serverA (fictive ip: 120.230.140.150), so that serverA is the one sending those mails to the world. Note that serverA, serverB en serverC are NOT in the same (local) network. Is it possible? And if so, what do I need to do to make it work as described?
