What best practices should be followed when handling errors in PHP scripts that interact with external services like email servers?

When handling errors in PHP scripts that interact with external services like email servers, it is important to use try-catch blocks to catch any exceptions that may occur. Additionally, it is recommended to log errors for debugging purposes and to provide meaningful error messages to users. 

try {
    // Code to interact with external email server
} catch (Exception $e) {
    error_log('Error interacting with email server: ' . $e->getMessage());
    echo 'An error occurred while sending the email. Please try again later.';
}
