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.
