NAME

relaytest - attempt to use SMTP to relay to a DSBL-compliant host

SYNOPSIS

relaytest [-v] <ip address[:port]>

DESCRIPTION

relaytest attempts to connect to the specified <ip address> on the specified port (default is port 25) and uses a variety of tests to attempt to relay through the host.

In the tests below, source.com is sender_domain from dsbl.conf(5) and sender is sender_user.

Non-domain-specific tests:

MAIL FROM:<sender@source.com>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<sender@source.com>
RCPT TO:<"listme@dsbl.org">

MAIL FROM:<sender@source.com>
RCPT TO:listme@dsbl.org

MAIL FROM:<sender@source.com>
RCPT TO:<dsbl.org!listme>

MAIL FROM:<nobody>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<nobody>
RCPT TO:<"listme@dsbl.org">

MAIL FROM:<nobody>
RCPT TO:listme@dsbl.org

MAIL FROM:<nobody>
RCPT TO:<dsbl.org!listme>

MAIL FROM:<source.com!sender>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<source.com!sender>
RCPT TO:<"listme@dsbl.org">

MAIL FROM:<source.com!sender>
RCPT TO:listme@dsbl.org

MAIL FROM:<source.com!sender>
RCPT TO:<dsbl.org!listme>

MAIL FROM:<>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<>
RCPT TO:<"listme@dsbl.org">

MAIL FROM:<>
RCPT TO:listme@dsbl.org

MAIL FROM:<>
RCPT TO:<dsbl.org!listme>

relaytest then builds a list of possible domains, including "[127.0.0.1]", "localhost", [<ip address>], and any other domains that can be derived from reverse DNS of the IP or the SMTP greeting.

Domain specific tests:

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<"listme@dsbl.org">

MAIL FROM:<nobody@DOMAIN>
RCPT TO:listme@dsbl.org

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<listme%dsbl.org@DOMAIN>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<listme%dsbl.org>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<"listme%dsbl.org">

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<listme@dsbl.org@DOMAIN>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<"listme@dsbl.org"@DOMAIN>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<@DOMAIN:listme@dsbl.org>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<dsbl.org!listme>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<dsbl.org!listme@DOMAIN>

MAIL FROM:<DOMAIN!nobody>
RCPT TO:<dsbl.org!listme>

MAIL FROM:<DOMAIN!nobody>
RCPT TO:<dsbl.org!listme@DOMAIN>

MAIL FROM:<nobody@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<postmaster@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<administrator@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<sales@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<info@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<webmaster@DOMAIN>
RCPT TO:<listme@dsbl.org>

MAIL FROM:<listserv@DOMAIN>
RCPT TO:<listme@dsbl.org>

relaytest then tries a variety of SMTP AUTH methods to try to relay a message through the target server.

The envelopes used for these tests are always:

MAIL FROM:<sender@source.com>
RCPT TO:<listme@dsbl.org>

The SMTP AUTH methods tried are as follows:

AUTH LOGIN, user=/webmaster, password=(null)
AUTH LOGIN, user=admin, password=admin
AUTH LOGIN, user=administrator, password=(null)
AUTH LOGIN, user=test, password=test
AUTH NTLM (anonymous)

OPTIONS

-v
Verbose mode. Details of the SMTP transaction are written to standard output.
