How to Replace PHP mail() with SMTP in Laravel Print

If you're using Laravel with Prabhu Host and want to ensure your emails are reliably delivered, it's recommended to switch from the default PHP mail() function to SMTP. SMTP provides better authentication and security for outgoing mail, and works seamlessly with Laravel.

Here’s a step-by-step guide to implement SMTP-based email sending in Laravel:

Step 1: Install SwiftMailer (if using older Laravel versions)

Most Laravel versions already include SwiftMailer by default. If it's not installed, you can add it manually:

composer require swiftmailer/swiftmailer

For Laravel 9 and above, Laravel uses Symfony Mailer instead of SwiftMailer, so this step might be unnecessary.

Step 2: Configure SMTP in the `.env` File

Open your Laravel project’s .env file and update the following lines with your SMTP credentials:

Use an App Password for Gmail instead of your regular login password.

Step 3: Update Laravel Mail Configuration

In config/mail.php, make sure the mailer is using SMTP by default:

'driver' => env('MAIL_MAILER', 'smtp'),

You may also review the mailers array and ensure smtp is configured properly if you're on Laravel 8 or later.

Step 4: Update Your Email-Sending Code

Use Laravel’s Mail facade to send emails instead of the native mail() function.

This will create a file in app/Mail/YourMailClass.php, where you can define the email subject, body, and view.

Test Your SMTP Setup

To confirm everything works:

Trigger an email send from your application.
Check your inbox or use a test email address.
Check Laravel logs (storage/logs/laravel.log) for errors if no email is received.

Conclusion

Replacing the PHP mail() function with SMTP in Laravel improves your email deliverability and ensures better security. Whether you're using Gmail, Outlook, Zoho, or your Prabhu Host business email, Laravel's SMTP integration provides a robust and professional solution for all your email needs.
