What are the potential challenges of sending emails from a local server using PHP?

One potential challenge of sending emails from a local server using PHP is that the emails may be flagged as spam by the recipient's email service provider. To mitigate this issue, you can set up proper email authentication, including SPF, DKIM, and DMARC records for your domain. 

// Example code for setting up SPF, DKIM, and DMARC records in PHP
$headers = 'From: yourname@yourdomain.com' . "\r\n" .
    'Reply-To: yourname@yourdomain.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

// Set up SPF, DKIM, and DMARC records
ini_set('sendmail_from', 'yourname@yourdomain.com');
ini_set('sendmail_path', '/usr/sbin/sendmail -t -i -fyourname@yourdomain.com');
