DevBrothers SMTP

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 (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.
