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.
