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.
