Set up a Mail Server With PostfixAdmin on Ubuntu 18.04

In this tutorial, we will cover the steps needed for installing a mail server using Postfix, Dovecot, SQLite, and PostfixAdmin on Ubuntu 18.04.

  • PostfixAdmin is a free web-based interface. With PostfixAdmin, we can configure and manage a Postfix-based email server for many users.
  • Postfix is a Mail Transfer Agent (MTA) that relays mail between different mail servers across the Internet.
  • Dovecot is a popular Local Delivery Agent (LDA) that deliver mail received from postfix into their final destinations (mailboxes, programs, etc..)

With these three packages combined, your server will be ready to send and receive emails, along with a web-based interface for managing your email server. Let’s begin.
