Walt, Some questions before answering yours.
1. Is the MX record for "one mail domain" pointed to two different server that’s located at US and EU ? 2. What you're wanting to do is, storing the same data on two different areas?(Like US and AU?) I once did store same data on two different areas using Lefthand by HP, and another using DRBD. I don’t know if Lefthand is still available or not. -----Original Message----- From: owner-postfix-us...@postfix.org <owner-postfix-us...@postfix.org> On Behalf Of Walt CH Sent: Wednesday, October 27, 2021 5:10 PM To: postfix-users@postfix.org Subject: question for the mail architecture Hello For our company's global design, we have the MX servers (postfix) on both the US and the EU. When the two MX servers receive the messages, how to store the messages into a separated area such as the AU? Thank you.
