It configures the PHPMailer instance bundled with WordPress on the `phpmailer_init` hook, so every plugin and theme that calls` wp_mail()` benefits automatically. Optionally, you can also send a plain-text copy of each email to a Telegram chat( success and/or failure). Telegram notifications are disabled by default and only run when you enable them and provide a bot token and chat ID. #### 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 SMTP settings * **Delivery log** — last 200 messages with sent/failed status and error text * **Telegram copies** — optional plain-text copy of emails to a Telegram chat ( opt-in) * **Secure secrets** — optional `DBSMTP_PASSWORD`, `DBSMTP_TELEGRAM_BOT_TOKEN`, and `DBSMTP_TELEGRAM_CHAT_ID` constants in `wp-config.php` * **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 connects only to services that **you** configure. No data is sent to DevBrothers. #### 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 email API — 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 #### Telegram Bot API (optional) When Telegram notifications are enabled, the plugin sends a plain-text summary of the email (site name, URL, From, To, subject, body text, and optional error message) to the Telegram Bot API endpoint `https://api.telegram.org/bot{token}/sendMessage`. Data is sent only when: * the Telegram toggle is enabled in settings, and * a bot token and Chat ID are configured (in settings or via `wp-config.php` constants), and * the corresponding notify option (success and/or failure) is enabled. Bot token and Chat ID are stored in your WordPress database, or in the `DBSMTP_TELEGRAM_BOT_TOKEN`/` DBSMTP_TELEGRAM_CHAT_ID` constants in `wp-config.php`. They are used only to call the Telegram Bot API. * Service provider: Telegram FZ-LLC * Terms: https://telegram.org/tos/bot-developers * Privacy: https://telegram.org/privacy #### 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. ## Screenshots [⌊SMTP connection settings with provider presets⌉⌊SMTP connection settings with provider presets⌉[ SMTP connection settings with provider presets [⌊Telegram notification settings⌉⌊Telegram notification settings⌉[ Telegram notification settings ## 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. 6. (Optional) Open the **Telegram** section, enable notifications, enter bot token and Chat ID, then send a Telegram test. ## 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. ### How do I enable Telegram copies of emails? 1. Create a bot with [@BotFather](https://t.me/BotFather) and copy the bot token. 2. Start a chat with the bot (send `/start`), or add it to a group/channel. 3. Get your Chat ID (for example via `getUpdates` or a helper bot such as `@userinfobot`). 4. In **DevBrothers SMTP Telegram**, enable notifications, paste the token and Chat ID, choose success and/or failure, and save. 5. Click **Send Telegram test**. ### Where do I store secrets securely? You can define constants in `wp-config.php` instead of storing values in the database: ``` define('DBSMTP_PASSWORD', 'your-smtp-password'); define('DBSMTP_TELEGRAM_BOT_TOKEN', '123456:ABC...'); define('DBSMTP_TELEGRAM_CHAT_ID', '123456789'); ``` When a constant is defined, the matching field in the settings UI is hidden and the constant value is used. ### Does Telegram receive the full email body? Yes, when enabled. The plugin sends a plain-text version (HTML tags stripped) truncated to Telegram’s message length limit. Attachments are not uploaded — only the attachment count is mentioned. ### 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. Telegram notifications can still run independently if enabled. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “DevBrothers SMTP” is open source software.
