WP SMTP Config: Set SMTP settings in config files for secure email delivery.

This plugin replaces the default PHP mail() function with an external SMTP server for sending emails. It is designed for developers and site administrators who want to keep SMTP credentials out of the database and away from other admin users. Configuration is done entirely in the config file, making it suitable for multisite installations where settings need to be applied once across the network.

Config file setup: All SMTP settings are defined in the config file using constants. No settings page exposes credentials to other admins.
Multisite support: Works with WordPress MU. Place settings once in the config file and activate the plugin network-wide.
Custom from and reply-to addresses: Define a custom sender name and email, plus a separate reply-to address, directly in the config file.
Encryption options: Supports TLS and SSL encryption for secure email transmission.
Built-in test page: A test page under Settings > SMTP lets you verify the configuration without sending a real email.
