Stream incoming emails to user-configured webhook endpoints through Cloudflare Edge Relay. Conceal backend server IP address, protect against SSRF, and verify payload authenticity.
Direct outbound webhooks from backend servers expose origin IP addresses in destination server logs, leaving cloud infrastructure vulnerable to tracing and targeted attacks. AliasMail uses a 3-Layer Edge Relay architecture powered by Cloudflare Workers to proxy outbound webhook requests.
Destination servers only log Cloudflare edge IP addresses (104.28.x.x / 2400:cb00::), completely concealing backend NestJS server IPs, hosting providers, and internal topology.
Every webhook dispatch includes an HMAC-SHA256 signature header (X-AliasMail-Signature) computed using Web Crypto API. Recipients can verify signature authenticity using their custom secret key while receiving sub-50ms real-time email payloads.
