/**
* AgenticMail Outbound Relay — Cloudflare Worker
*
* Relays outbound email through an SMTP server (e.g. Gmail) on port 465.
* Cloudflare blocks port 25 (direct MX delivery) but allows 465/587.
* We use Gmail SMTP as the relay — the email FROM is secretary@2sabi.net
* and Gmail handles the actual delivery with its clean IP infrastructure.
*
* Required env vars:
* OUTBOUND_SECRET - shared secret for authenticating HTTP requests
* SMTP_HOST - relay SMTP host (default: smtp.gmail.com)
* SMTP_PORT - relay SMTP port (default: 465)
* SMTP_USER
