Actra SMTP is designed for simplicity and performance. It uses the native PHPMailer library included in WordPress core to route all emails through your preferred SMTP server.<\/p>\n\n\n

    \n
  1. Upload the actra-smtp folder to the \/wp-content\/plugins\/ directory.<\/li>\n
  2. Activate the plugin through the 'Plugins' menu in WordPress.<\/li>\n
  3. Configure your SMTP settings under 'Settings > Actra SMTP'.<\/li>\n<\/ol>\n\n\n
    \n

    Does this plugin support Gmail\/Outlook?<\/h3><\/dt>\n

    Yes, as long as you provide the correct SMTP host and credentials.<\/p><\/dd>\n

    Can I store SMTP settings in wp-config.php instead of the database?<\/h3><\/dt>\n

    Yes. SMTP settings can be defined in wp-config.php using constants. Constants take priority over values stored in the database.<\/p>\n\n

    Available constants:<\/p>\n\n

    define('ACTRA_SMTP_FROM_EMAIL', 'noreply@example.com');\ndefine('ACTRA_SMTP_HOST', 'smtp.example.com');\ndefine('ACTRA_SMTP_USERNAME', 'user@example.com');\ndefine('ACTRA_SMTP_PASSWORD', 'your-smtp-password');\ndefine('ACTRA_SMTP_PORT', 587);\ndefine('ACTRA_SMTP_TLS', true);<\/p>\n\n

    You may define individual constants, but using the full set is recommended to avoid mixed configuration sources. When a constant is defined, the matching field in the plugin settings screen is disabled and cannot be changed there.<\/p><\/dd>\n

    Can I define an empty SMTP password in wp-config.php?<\/h3><\/dt>\n

    Yes. For local environments that do not require SMTP authentication, such as some DDEV or Mailpit setups, you can intentionally define empty credentials:<\/p>\n\n

    define('ACTRA_SMTP_USERNAME', '');\ndefine('ACTRA_SMTP_PASSWORD', '');<\/p><\/dd>\n

    How do wp-config.php constants work in WordPress multisite?<\/h3><\/dt>\n

    In WordPress multisite installations, all sites share the same wp-config.php file. Any ACTRA_SMTP_* constant defined there applies network-wide to all sites in the multisite network.<\/p>\n\n

    Database settings remain site-specific. This means each site can have its own SMTP settings in the database unless a matching ACTRA_SMTP_* constant is defined.<\/p>\n\n

    If you need different SMTP settings for each site, configure them through each site's settings screen and avoid defining global ACTRA_SMTP_* constants.<\/p><\/dd>\n

    Is the SMTP password displayed in the WordPress admin area?<\/h3><\/dt>\n

    No. The saved SMTP password is never displayed in the settings screen. If a password exists in the database, the field remains empty and can be left unchanged.<\/p><\/dd>\n

    What happens to passwords saved before this update?<\/h3><\/dt>\n

    Existing plaintext passwords remain supported for backwards compatibility. When a new password is saved through the settings screen, it is stored encrypted in the WordPress database.<\/p><\/dd>\n

    Is it compatible with other mail plugins?<\/h3><\/dt>\n

    You should only have one SMTP plugin active at a time to avoid conflicts.<\/p><\/dd>\n\n<\/dl>\n\n\n
