SMTP Tunnel Proxy
A high-speed covert tunnel that disguises TCP traffic as SMTP email
SMTP Tunnel Proxy is a high-speed covert tunneling proxy that disguises regular TCP traffic as legitimate SMTP email communication to evade deep packet inspection (DPI) firewalls and censorship systems. It implements a SOCKS5 proxy interface on the client that wraps outbound traffic into an SMTP-like handshake (EHLO, STARTTLS, AUTH) and encrypted payload, making the session appear to DPI systems as a normal email exchange. -
