Setting up a Postfix Backup MX Server
When it comes to ensuring the reliability of your email server, having a backup MX server can be a lifesaver. In the event that your primary server goes down, a backup MX server can store and forward incoming emails until the primary server is back online. In this article, we will guide you through the process of setting up a Postfix backup MX server to ensure that your email communication remains uninterrupted.
What is a Backup MX Server?
A backup MX server, also known as a secondary mail exchanger, is a mail server that acts as a contingency plan in case the primary mail server becomes unavailable.
