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. AUTHOR
