== Installation ==

1. Upload the `oderland-smtp-postal-mailer` folder to the `/wp-content/plugins/` directory
2. Activate the plugin through the 'Plugins' menu in WordPress

5. Send a test email to verify your configuration

== Frequently Asked Questions ==

= How do I configure SMTP? =

Go to Settings > Oderland SMTP & Postal Mailer > Accounts and click "Add Account". Select SMTP as the service type and enter your SMTP server details including host, port, username, and password.

= How does the failover work? =

Accounts are tried in priority order (lower number = higher priority). If sending fails with a temporary error, the plugin retries with exponential backoff. If all retries fail, it moves to the next account.

= What gets logged? =

By default, the plugin logs email headers, recipients, and subjects. You can optionally enable body logging. Logs are automatically removed after 30 days (configurable).

= How do I set up Postal webhooks? =

When you create a Postal account, the plugin generates a webhook URL. Add this URL in your Postal server's webhook settings to receive delivery status updates.

= Is my SMTP password secure? =

Yes. All sensitive credentials (SMTP passwords, API keys) are encrypted using AES-256-CBC before storage.
