## Descrição

Most SMTP plugins confirm that a test message left the server. Shop owners still
do not know why an order email failed.

Design Cart SMTP is a diagnostic SMTP layer for WordPress and WooCommerce. It sends
mail through an authenticated mailbox, then shows what the mail server actually 
answered.

#### What makes it different

 * Mapped SMTP errors (authentication, TLS, connection, certificate, sender/relay,
   recipient, rate limit) instead of a generic failure
 * Full SMTP transcript (password redacted) plus the raw PHPMailer message
 * WooCommerce-style test using the store email wrapper — no fake orders
 * Send log of the last 100 messages with source (WordPress / WooCommerce / test)
   and error text
 * Presets for Gmail, Outlook, and Polish hosts (home.pl, nazwa.pl, OVH, cyber_Folks)
 * Force From so the WooCommerce envelope matches the SMTP mailbox
 * WooCommerce HPOS compatible; templates stay in WooCommerce  Settings  Emails

This plugin only changes transport. It does not replace WooCommerce email templates
or marketing mail tools.

## Instalação

 1. Upload the `design-cart-smtp` folder to `/wp-content/plugins/`.
 2. Activate the plugin from the **Plugins** screen.
 3. Go to **Settings  Design Cart SMTP**.
 4. Enter your SMTP details, enable SMTP, and send a test email.
 5. Read the mapped errors, PHPMailer message, and SMTP transcript if the test fails.

## Perguntas frequentes

### How is this different from other SMTP plugins?

The focus is diagnosis, not another settings form. A failed send returns mapped 
SMTP errors, the PHPMailer message, and a password-redacted transcript. WooCommerce
shops also get a store-style test and a send log that records which email type failed.

### Does it work with WooCommerce?

Yes. WooCommerce sends mail through wp_mail(). This plugin configures PHPMailer (
SMTP), can force the From header, and can send a WooCommerce-style test without 
creating an order.

### Can I edit store email content here?

No. Templates and per-email toggles stay in **WooCommerce  Settings  Emails**. This
plugin only changes transport.
