Resonanz Email Rerouting makes testing websites safer by rerouting outgoing emails to a specific address based on the current environment (local, development, staging, production), as defined by the WP_ENVIRONMENT_TYPE<\/code> constant in your wp-config.php<\/code> file.<\/p>\n\n

Features<\/h4>\n\n
    \n
  • Reroute emails based on WP_ENVIRONMENT_TYPE<\/code>.<\/li>\n
  • Enable or disable email rerouting on a per-environment basis.<\/li>\n
  • Add domains to a whitelist to avoid rerouting mail sent to those domains.<\/li>\n
  • Add one or more email addresses to which emails should be rerouted.<\/li>\n
  • Grant different user roles access to the plugin settings.<\/li>\n
  • Add a prefix to the subject line of rerouted emails.<\/li>\n
  • Append a message to the body of rerouted emails.<\/li>\n
  • Display a notification to the logged-in user when an email has been rerouted.<\/li>\n
  • Enable or disable simple email logging, including a retention policy.<\/li>\n
  • Easily export and import settings in JSON format.<\/li>\n
  • Works with Gravity Forms and Contact Form 7.<\/li>\n<\/ul>\n\n\n
      \n
    1. Configure the environment variable in wp-config.php<\/code> (see FAQ below).<\/li>\n
    2. Upload the entire resonanz-email-rerouting<\/code> folder to the \/wp-content\/plugins\/<\/code> directory.<\/li>\n
    3. Activate the plugin through the 'Plugins' menu in WordPress.<\/li>\n<\/ol>\n\n\n
      \n

      How do I set the environment variable?<\/h3><\/dt>\n

      You can set the environment variable in your wp-config.php<\/code> file. Add a line like the following:<\/p>\n\n

      define('WP_ENVIRONMENT_TYPE', 'local');\n<\/code><\/pre>\n\n
      For further information, see the WordPress documentation: https:\/\/developer.wordpress.org\/apis\/wp-config-php\/#wp-environment-type<\/p><\/dd>\n
      Does this plugin work with other email related plugins?<\/h3><\/dt>\n
      We cannot guarantee that this plugin will function as expected if you use other email-related plugins.<\/p>\n\n
      If you have a plugin that makes use of SMTP, you should probably disable it for this plugin to work correctly.<\/p>\n\n
      If you encounter specific issues, please let us know.<\/p><\/dd>\n

      1.5.0<\/h4>\n\n
        \n
      • Hardened sanitization of saved settings: role permission keys are now validated against the roles WordPress actually offers.<\/li>\n
      • Settings import now runs through the same sanitizer as the settings form, so imported files can no longer store unsanitized values.<\/li>\n
      • Prefixed the AJAX, admin-post and log-purge action names to avoid collisions with other plugins.<\/li>\n
      • Prefixed the email log meta keys. Existing logs are migrated automatically on upgrade.<\/li>\n
      • Added nonce verification to both AJAX endpoints.<\/li>\n
      • Fixed settings import rejecting every file. The uploaded file is now identified correctly.<\/li>\n
      • Fixed settings import failing on Windows servers because the upload path was altered before use.<\/li>\n
      • Renamed an internal helper that shadowed WordPress core's sanitize_email()<\/code>.<\/li>\n
      • Updated \"Tested up to\" for WordPress 7.1.<\/li>\n<\/ul>\n\n
        1.4.0<\/h4>\n\n
          \n
        • Hardened input handling and output escaping throughout the plugin (Plugin Check compliance).<\/li>\n
        • Fixed per-environment settings (whitelisted domains and reroute addresses) not being sanitized on save.<\/li>\n
        • Fixed role capabilities lagging one save behind when permissions were changed.<\/li>\n
        • Fixed the bundled German translation not loading (translation files renamed to match the text domain).<\/li>\n
        • Added cleanup on deactivation (scheduled event) and uninstall (options, capability, and logged data).<\/li>\n
        • Switched to safe redirects and gmdate()<\/code>, and added a readme.txt<\/code>.<\/li>\n<\/ul>\n\n
          1.3.1<\/h4>\n\n
            \n
          • Fixed rerouted emails crashing when wp_mail()<\/code> recipient, sender, subject, or message values were passed in non-string formats.<\/li>\n<\/ul>\n\n
            1.3.0<\/h4>\n\n
              \n
            • Validation of entered email addresses in the WordPress backend.<\/li>\n
            • Performance optimizations.<\/li>\n<\/ul>\n\n
              1.2.5<\/h4>\n\n
                \n
              • Fixed a minor namespace issue that was causing an error when purging logs.<\/li>\n<\/ul>\n\n
                1.2.4<\/h4>\n\n
                  \n
                • Make sure post slug is not empty.<\/li>\n
                • Some other minor code improvements.<\/li>\n<\/ul>\n\n
                  1.2.3<\/h4>\n\n
                    \n
                  • Added information to allow the plugin to be updated via Git Updater.<\/li>\n<\/ul>\n\n
                    1.2.2<\/h4>\n\n
                      \n
                    • First public release of the plugin.<\/li>\n<\/ul>","raw_excerpt":"Reroute WordPress emails to a test address per environment so testing never mails real users.
