 (username, password, recipient address, cookie server, ...) are
 expected to be found in environment variables.  Run \fBproxycheck\fR
 with \fB\-h\fR option to see a list of recognized variables and
-their default values.  By default, \fBproxycheck\fR will anonimously
+their default values.  By default, \fBproxycheck\fR will anonymously
 submit all found proxies to unconfirmed.dsbl.org (which isn't very
 useful).  For trusted DSBL user, at least DSBL_USER and DSBL_PASS
 variables should be set properly.
 .RE
-
 .IP "\fB\-p\fR \fIproto_port_spec\fR"
 specifies protocol and ports to connect to.  If not given, \fBproxycheck\fR
 will try it's built-in default list.  This option may be specified more
 than once.   See below for \fIproto_port_spec\fR.  If \fIproto_port_spec\fR
 is specified for a single host to check, it applies to that host only,
 and no protocols/ports in default list will be checked for that host.
-
 .IP \fB\-D\fR
 do not reset default port list when using \fB\-p\fR option, but prepend
 new ports to it instead.
-
 .IP \fB\-a\fR
 use more "advanced" ports/protocols.  The more \fB\-a\fR's given, the more
 ports/protocols will be probed.  For a complete list of all ports and protocols
 and their level, execute \fBproxycheck\fR with \fB\-h\fR option.
-
 .IP "\fB\-t\fR \fItimeout\fR"
 a timeout, in secounds, for every operation.  Default value is 30 secounds.
 The timer starts at the connection attempt to the proxy itself, after
 sending the "connect" command to the proxy and so on.
-
 .IP "\fB\-m\fR \fImaxconn\fR"
 Do not attempt to make more than \fImaxconn\fR parallel connections.
 By default, maximum number of parallel connections limited by the
 operating system and on most systems it is around 1000.
-
 .IP "\fB\-M\fR \fImaxhconn\fR"
 Do not make more than \fImaxhconn\fR parallel connections to the
 same host (default is unlimited).  This may be useful for overloaded
 proxies which can't handle many parallel connections using different
 ports/protocols, but may significantly slow down the whole process.
-
 .IP \fB\-s\fR
 when an open proxy is found on a given IP, stop probing for other
 ports/protocols for this IP.  Best used when many IPs are tested,
 and/or with \fB\-M\fR option.  This is because currently, \fBproxycheck\fR
 will not make any \fInew\fR connections to such host, but will wait
 for already active connections to complete.
-
 .IP "\fB\-b\fR \fIbindaddr\fR"
 use \fIbindaddr\fR as a source address for all outgoing connections.
-
 .IP \fB\-n\fR

 to writing about open proxies, in a form

 proxy server was found.  In case of incorrect usage, it will exit
 with code 1.  If no open proxies where found, \fBproxycheck\fR
 will return 0.
+
+.SH EXAMPLES
+In the simplest case, specify:
+
+.nf
+  proxycheck -vv -ddsthost:dstport -c chat::"waitstr" \fIlist-of-IPs\fR
+.fi
+
+where
+\fBdsthost\fR is the host and \fBdstport\fR is the port number of the
+destination system, and \fBwaitstr\fR is a string to look for from the remote
+system. If you decide to connect to your own mailserver (which is quite
+logical, since most proxy abuse nowadays is to send spam to your mailserver),
+connect to it first using telnet and see which SMTP greeting string it prints
+out upon connection, and use this string as \fBwaitstr\fR.  For example, if
+your mailserver is \fImail.example.com\fR, the following may apply:
+
+.nf
+  $ \fBtelnet mail.example.com 25\fR
+  Telnet: trying 127.0.0.1... connected.
+  250 mail.example.com ESMTP welcome
+  \fBQUIT\fR
+.fi
+
+In this case, \fBproxycheck\fR's command line may look as follows:
+
+.nf
+  proxycheck -vv -d mail.example.com:25 \\
+   -c chat::"250 mail.example.com ESMTP welcome" \fIlist-of-IPs\fR
+.fi
+
+Another usage scenario is to automatically submit all open proxies to
+DSBL.org-style blocklists.  For this, specify \fB-c dsbl\fR and set up
+environment variables for dsbl client.  The variables \fBDSBL_USER\fR and
+\fBDSBL_PASS\fR are required for non-anonymous DSBL submissions, for anonymous
+submissions to the \fIunconfirmed.dsbl.org\fR defaults are sufficient. To
+submit a proxy to DSBL.org, set destination to the mail exchanger of
+\fIlistme.dsbl.org\fR domain, currently \fImx.listme.dsbl.org\fR.  For example:
+
+.nf
+  DSBL_USER=username DSBL_PASS=password ./proxycheck -vv \\
+   -dmx.listme.dsbl.org:25 -cdsbl \fIproxyhost\fR
+.fi
