## Description

**DevBrothers SMTP** reroutes the standard WordPress mailer (`wp_mail`) through 
your own SMTP server instead of the unreliable PHP `mail()` function. It configures
the PHPMailer instance bundled with WordPress on the `phpmailer_init` hook, so every
plugin and theme that calls `wp_mail()` benefits automatically.

This plugin focuses on a simple, privacy-friendly setup for Russian mail providers
and small sites. All core features are free — no premium tier, no upsells, no external
email APIs.

#### Key Features

 * **One-click presets** — Yandex Mail and Mail.ru (host, port, SSL) filled in automatically
 * **Custom SMTP** — manual host, port, TLS or SSL, optional authentication
 * **Custom sender** — optional From email and From name, with a force option
 * **Test email** — one-click send to verify settings
 * **Delivery log** — last 200 messages with sent/failed status and error text (
   free; many competitors charge for this)
 * **Secure password** — optional `DBSMTP_PASSWORD` constant in `wp-config.php` 
   instead of the database
 * **DevBrothers Admin Panel** — settings inside the unified DevBrothers interface

#### Requirements

 * WordPress 5.8+
 * PHP 7.4+
 * [DevBrothers Admin Panel](https://wordpress.org/plugins/devbrothers-admin-panel/)(
   required dependency)

### External services

This plugin sends email through an SMTP server that **you** configure in the settings.
No email is sent to DevBrothers or any service we operate.

#### Your SMTP server

When SMTP delivery is enabled, WordPress emails (recipients, subject, body, attachments,
and headers) are transmitted to the host, port, and account you specify. The plugin
does not connect to a fixed third-party provider — you choose the server (for example
Yandex Mail, Mail.ru, your hosting provider, or another SMTP service).

Authentication credentials (username and password) are stored in your WordPress 
database or in the `DBSMTP_PASSWORD` constant in `wp-config.php`. They are used 
only to connect to your configured SMTP server.

 * Service provider: defined by you (the site administrator)
 * Terms and privacy: depend on your chosen SMTP provider

#### Local delivery log

The plugin stores a log of sent and failed messages (recipient, subject, status,
error text) in a database table on your site. This data is **not** transmitted to
DevBrothers or any external service.

## Installation

 1. Install and activate **DevBrothers Admin Panel** from WordPress.org (or install
    it when prompted).
 2. Install and activate **DevBrothers SMTP**.
 3. Go to **DevBrothers  SMTP**.
 4. Choose **Yandex Mail**, **Mail.ru**, or **Custom server**, enter your credentials,
    and save.
 5. Send a test email to verify the configuration.

## FAQ

### How do I set up Yandex Mail?

Select **Yandex Mail** in the provider dropdown. Use your full Yandex email as the
username. If two-factor authentication is enabled, create an app password in your
Yandex ID settings. The From address should match your mailbox.

### How do I set up Mail.ru?

Select **Mail.ru** in the provider dropdown. Use your full Mail.ru email as the 
username. If two-factor protection is enabled, use an app-specific password. The
From address should match your mailbox.

### Where do I store the SMTP password securely?

You can define a constant in `wp-config.php` instead of storing the password in 
the database:

    ```
    define('DBSMTP_PASSWORD', 'your-smtp-password');
    ```

When this constant is defined, the password field in the settings is hidden and 
the constant value is used.

### My emails go to spam. What should I check?

Make sure your sending domain has valid SPF, DKIM and DMARC records, and that the
From address matches your SMTP account.

### Why is DevBrothers Admin Panel required?

DevBrothers SMTP registers its settings page inside the DevBrothers admin UI. Install
Admin Panel from WordPress.org first.

### Does this plugin work when SMTP is disabled?

Yes. When the SMTP toggle is off, WordPress uses its default mail transport and 
this plugin does not alter PHPMailer settings.

### Is everything really free?

Yes. SMTP configuration, presets, test email, delivery log, and wp-config password
support are included at no cost. There is no premium version.
