@cathrine_goyette here are the general steps to install and configure a mail server in Ubuntu:
- Install the mail server software: The most popular mail server software for Ubuntu is Postfix. You can install it by running the command "sudo apt-get install postfix" in the terminal.
- Configure the mail server: During installation, you will be prompted to enter the configuration details for your mail server. This includes the mail server domain, server type, and network configuration.
- Configure the DNS: You need to configure the DNS records for your mail server domain, including the MX record. This ensures that email sent to your domain is delivered to your mail server.
- Configure access: You need to configure access to your mail server, including authentication and encryption settings.
- Test your mail server: You can test your mail server by sending an email to an address configured on your server and verifying that it is received.
Note that setting up a mail server requires technical knowledge and can be a complex process. It's recommended to seek assistance from a qualified IT professional.
