NAME
httptest - attempt to use an HTTP proxy to relay to a DSBL-complaint
host
SYNOPSIS
httptest <http ip> <http port>
DESCRIPTION
httptest attempts to connect to port <http port> on <http ip> and relay
through the host.
It attempts to connect to the target_domain mail server directly to
send mail, and also to relay through 127.0.0.1 on the host. For each
server, it tries all of: GET, POST, CONNECT.
It works by embedding SMTP commands in the HTTP request header, which
are then copied through to the mail server. There is extra junk in the
HTTP header, but most SMTP servers ignore it. If a server is open to
this type of relaying, it is highly likely that the relay will be
anonymized and there will be no way to track back the sender (save
possibly proxy logs).
As of version 0.9.5, httptest attempts to use the CONNECT method as
intended to form an actual SMTP conversation through the proxy.
