Step 2: Install Required Packages

After updating your server, you’ll need to install the necessary packages for your mail server. The following packages are required:

You can install these packages using the following command:

Command	Description

Step 3: Configure Postfix

Edit the dovecot.conf file and configure the following parameters:
