Send every site email through a fully configurable SMTP server managed from the WordPress dashboard.

== Description ==

SMTP (by ROBOTSTXT) replaces WordPress' native mail delivery with a secure SMTP connection and detailed guidance. The plugin is built for marketing teams, agencies, and technical departments that need a clear, complete solution ready for multisite installations.

= Guided PHPMailer configuration =

* Routes `wp_mail()` through PHPMailer in SMTP mode with support for credentials, custom ports, and the `None`, `SSL`, or `TLS` encryption methods.
* Adds inline help text with practical examples in every field: host, port, username, password, sender email, and sender name.
* Automatically changes the port when it matches the default value for the selected encryption type (25, 465, or 587).
* Lets you set default sender information for the site to keep a consistent identity across outgoing messages.

= Tools for support and marketing teams =

* **Settings → SMTP → Test** screen for sending manual test emails and confirming the connection to the server.
* **Tools** panel packed with diagnostics: automatic MX lookup, SPF/DKIM/DMARC checks, extended SMTP server diagnostics, and DNS reputation monitoring.
* Caches results from each tool for 24 hours (with a manual refresh option) to streamline recurring tasks for your team.

= Comprehensive delivery logs =

* Saves the subject, recipients, headers, content, and attachments for every email sent.
* Browse logs from **Settings → SMTP → Logs** with pagination and access to the details of each delivery.
* Configure automatic cleanup by maximum entries or age in days, plus an instant "Clear all" button to wipe the history.

= Multisite-ready configuration =

* Choose whether the configuration applies to the entire network or individually per site.
* Dedicated forms in both the network dashboard and each site to edit, test, and share credentials securely.

== Installation ==

1. Upload the plugin folder to `wp-content/plugins/`.
2. Activate **SMTP (by ROBOTSTXT)** from the **Plugins** menu in the WordPress dashboard.
3. Open **Settings → SMTP** (or **Network Settings → SMTP** in multisite) to enter your connection details.

== Frequently Asked Questions ==

= Do I need credentials to send email? =

Enter a username and password only if your provider requires them. If the server accepts unauthenticated delivery, leave the fields blank and the plugin will send without credentials.

= Which encryption should I use? =

Select `None`, `SSL`, or `TLS` according to your provider's documentation. When you switch encryption, the plugin will automatically suggest the recommended port if you are using one of the standard values.

= How can I review the emails that were sent? =

Enable logging on the settings page and visit **Settings → SMTP → Logs** to open the paginated table of saved emails. From there you can inspect each entry, download attachments, and delete records.

= Does it work on a multisite network? =

Yes. From the network dashboard you can decide whether the configuration is global or site-specific. You can also run the tools and send test emails from the network or from each individual site.
