What are the best practices for setting up and configuring a local mail server for PHP development purposes?

Setting up a local mail server for PHP development purposes allows developers to test email functionality without sending actual emails to real recipients. One common way to achieve this is by using a tool like MailHog, which captures and displays emails sent by your PHP application on a local server.

// Example code snippet using MailHog for local mail server setup
// Install MailHog via a package manager like Homebrew or download the binary from the official website
// Start MailHog using the command line: `mailhog`
// Configure your PHP application to send emails to localhost:1025 (default MailHog port)
// Access the MailHog web interface to view captured emails: http://localhost:8025
