📬 Why SMTP is Better Than mail()
PHP’s native mail function isn’t always reliable due to spam filters, server restrictions, and lack of authentication. Using SMTP ensures secure, reliable delivery.

✅ Solution: Use PHPMailer or SwiftMailer

🔐 Security Tips:
Use SMTP authentication

Do not expose passwords in code

Sanitize user input in forms

Use CAPTCHA to prevent bots

Validate email addresses

🛠️ Troubleshooting Common Issues
"SMTP connect() failed": Check host and port

"Permission denied": Check file/folder permissions

"Headers already sent": Ensure no output before mail()

Emails not received? Check spam or server logs

🔁 Best Practices Recap
Always use SMTP for production

Use libraries like PHPMailer or SwiftMailer

Keep email content short and clean

Avoid spammy subject lines

Use real sender info and domain email

📈 Why This Matters for Developers
Email functionality is critical in:

Registration forms

Contact us pages

Password resets

Notifications

Order confirmations

If you're building anything dynamic in PHP, email capability is a must.
