Show HN: SMTP Tunnel – A SOCKS5 proxy disguised as email traffic to bypass DPI A fast SOCKS5 proxy that tunnels your traffic through what looks like normal SMTP email, bypassing Deep Packet Inspection firewalls. How it works: - Client runs a local SOCKS5 proxy (127.0.0.1:1080) - Traffic is sent to server disguised as SMTP (EHLO, STARTTLS, AUTH) - DPI sees legitimate email session, not a VPN/proxy Features: - One-liner install on any Linux VPS - Multi-user with per-user secrets and IP whitelists - Auto-generated client packages (just double-click to run) - Auto-reconnect on connection loss - Works with any app that supports SOCKS5 Tech: Python/asyncio, TLS 1.2+, HMAC-SHA256 auth GitHub: https://bit.ly/4aOjAKG https://bit.ly/4aOjAKG January 7, 2026 at 01:30AM
