/**
 * Plugin Name: RESPILON SMTP
 * Description: Routes all WordPress/WooCommerce mail through an SMTP relay when the
 *              SMTP_* env vars (Fly secrets) are present. Provider-agnostic: works with
 *              Brevo, Resend, Mailgun, Postmark, Gmail, etc. Until secrets are set this
 *              is a no-op (WordPress on Fly has no local MTA, so mail just doesn't send).
 *
 * Fly secrets to set (see README):
 *   SMTP_HOST, SMTP_PORT (default 587), SMTP_USER, SMTP_PASS,
 *   SMTP_SECURE (tls|ssl, default tls), SMTP_FROM (default hei@antiakne.no)
