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.

auth-relaytest - attempt to use authenticated SMTP to relay to a DSBL-compliant host
SYNOPSIS
auth-relaytest [-tv] ntlm <ip address[:port]>
auth-relaytest [-tv] (cram-md5|login) <username> <password> <ip address[:port]>
DESCRIPTION
auth-relaytest attempts to connect to the specified <ip address> on the specified port (default is port 25) and tries to use the supplied
authentication data to relay mail through the host.
auth-relaytest uses the sender_user, sender_domain, target_user, target_domain, and auth-message parameters from dsbl.conf(5) by default.
If the auth-message parameter is not present, the message parameter is used instead.
In the first mode of operation shown, auth-relaytest attempts to authenticate using anonymous NTLM authentication. A well-known bug in cer-
tain Microsoft SMTP server implementations (described at http://www.microsoft.com/technet/security/bulletin/MS02-011.asp) will allow relay-
ing for any client that authenticates in this way.
In the second form of operation, auth-relaytest attempts to authenticate using either the cram-md5 or login variant of SMTP AUTH, using the
supplied username and password.
OPTIONS -t Test mode. Instead of using the target_domain parameter from dsbl.conf(5), the test_target_domain parameter is used instead. This is
useful for sending a test message to yourself, perhaps to check that the server is actually relaying the messages.
-v Verbose mode. Details of the SMTP transaction are written to standard output.
