DESCRIPTION
Halaman manual ini mendokumentasikan secara ringkas spfquery command. It was written for the Debian®
pengedaran kerana program asal tidak mempunyai halaman manual.
spfquery performs Sender Policy Framework (SPF) authorization checks based on the command-
line arguments or data given in a file or on standard input. For information on SPF see
http://www.openspf.org.
PILIHAN
Options are divided into two groups: Data options, which must be given, though just enough
of them to specify a query; and control options, which are optional and control the local
policy, behaviour and output format of spfquery.
This programs follows the GNU getopt_long_only(3) command line syntax: Long options can be
given with one or two dashes and can be abbreviated to a prefix long enough to be non-
ambiguous. If an option starting with a single dash doesn't match a long option, it is
taken as a short option with a following parameter, if applicable. An equals sign between
the option name and the parameter is optional for both short and long options.

DIAGNOSTIK
The output ordinarily consists of four lines:
1. yang mengakibatkan kod;
2. yang penerangan, suitable for use in an SMTP response message, empty except when a
rejection (permanent or temporary) makes sense;
3. the header comment on its own;
4. the Received-SPF header field as defined in RFC 4408 section 7, incorporating the
ulasan tajuk.
If errors (including no SPF record found!) occur during processing, one or more error
blocks will be prepended. These start with “StartError“ and end with “EndError“.
The result codes and their corresponding exit codes are as follows:
1 - neutral
The sender domain explicitly makes no assertion about the alamat IP. This result
must be interpreted exactly as if no SPF record at all existed.
2 - lulus
. alamat IP is authorized to send mail for the sender domain.
3 - gagal
. alamat IP is tanpa kebenaran to send mail for the sender domain.
4 - softfail
. alamat IP is not authorized to send mail for the sender domain, but the sender
domain cannot or does not wish to make a strong assertion that no such mail can
ever come from it.
5 - tiada
No SPF record was found.
6 - kesilapan (Sementara)
A transient error occurred (e.g. failure to reach a DNS server), preventing a
result from being reached.
7 - tidak diketahui (permanent error)
One or more SPF records could not be interpreted.
