.SH NAME
relaytest \- attempt to use SMTP to relay to a DSBL-compliant host
.SH SYNOPSIS
.BI "relaytest [-v] <" "ip address" "[:" "port" "]>"
.SH DESCRIPTION
relaytest attempts to connect to the specified
.RI < "ip address" >
on the specified
.RI "" port ""
(default is port 25) and uses a variety of tests to attempt to relay through
the host.

In the tests below,
.B source.com
is
.I sender_domain
from
.BR dsbl.conf (5)
and sender
is
.IR sender_user .
.HP
Non-domain-specific tests:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

MAIL FROM:<>
.br
RCPT TO:<dsbl.org!listme>
.LP
relaytest then builds a list of possible domains, including
"[127.0.0.1]", "localhost",
.RI [< "ip address" >],
and any other domains that can be derived from reverse DNS
of the IP or the SMTP greeting.
.HP
Domain specific tests:

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

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

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

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

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

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

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

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

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

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

.br
.RB "RCPT TO:<dsbl.org!listme@" DOMAIN >

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