How to Configure PHP mail() or SMTP Authentication for Popular CMS Print

30

To ensure reliable email delivery, it’s best to use SMTP instead of the default mail() function. Here’s how to set it up for common CMS platforms:

WordPress (using WP Mail SMTP plugin)

Install WP Mail SMTP plugin
Go to Settings > WP Mail SMTP
Enter SMTP server: mail.yourdomain.com
Use port 465 and SSL encryption
Use your full email and password to authenticate

Joomla

Go to Global Configuration > Server
Set Mailer to SMTP
Enter SMTP server: mail.yourdomain.com
Set port to 465 with SSL
Enter your full email and password

Drupal

Use modules like SMTP Authentication Support or PHPMailer.

Why this matters: SMTP prevents emails from being flagged as spam and improves deliverability.
