       httptest  -  attempt  to use an HTTP proxy to relay to a DSBL-complaint


       httptest <http ip> <http port>


       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 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.
