NAME
spfquery - checks if an IP address is an SPF-authorized SMTP sender for a domain

VERSION
2.3

spfquery --helo|-h hostname --ip|-i ip-address [OPTIONS]

spfquery --file|-f filename|- [OPTIONS]

spfquery --version|-V

spfquery --help

DESCRIPTION
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>.

The --mail-from form checks if the given ip-address is an authorized SMTP sender for the
given envelope sender domain or email-address and "HELO" hostname (so-called "MAIL FROM"
check). If a domain is given, "postmaster" will be substituted for the localpart.

The --helo form checks if the given ip-address is an authorized SMTP sender for the given
"HELO" hostname (so-called "HELO" check).

The --file form reads "ip-address sender-address helo-hostname" tuples from the file with
the specified filename, or from standard input if filename is -.

The --version form prints version information of spfquery. The --help form prints usage
information for spfquery.

OPTIONS
The --mail-from, --helo, and --file forms optionally take any of the following additional
OPTIONS:

--debug
Print out debug information.

--default-explanation string
Use the specified string as the default explanation if the SPF record does not specify
an explanation string itself.

--guess spf-terms
Use spf-terms as a default record if no SPF record is found. This is a non-standard
feature.

--keep-comments
--no-keep-comments
Do (not) print any comments found when reading from a file or from standard input.

--local spf-terms
Process spf-terms as local policy before resorting to a default result (the implicit
or explicit "all" mechanism at the end of the domain's SPF record). For example, this
could be used for white-listing one's secondary MXes: "mx:mydomain.example.org".

--max-lookup-count n
Perform a maximum of n SPF record lookups. Defaults to 10.

--name hostname
Use hostname as the hostname of the local system instead of auto-detecting it.

--override domain=spf-record
--fallback domain=spf-record
Set overrides and fallbacks. Each option can be specified multiple times. For exam-
ple: "--override example.org='v=spf1 -all' --override '*.example.net'='v=spf1 a mx
-all' --fallback example.com='v=spf1 -all'". This is a non-standard feature.

--rcpt-to email-addresses
Automatically allow the secondary MXes of the comma-separated list of email-addresses.

--sanitize
--no-sanitize
Do (not) sanitize the output by condensing consecutive white-space into a single space
and replacing non-printable characters with question marks. Enabled by default.

--trusted
--no-trusted
Do (not) perform "trusted-forwarder.org" accreditation checking. Disabled by default.
This is a non-standard feature.

RESULT CODES
pass The specified IP address is an authorized mailer for the sender domain/address.

fail The specified IP address is not an authorized mailer for the sender
domain/address.

softfail The specified IP address is not an authorized mailer for the sender
domain/address, however the domain is still in the process of transitioning to
SPF.

neutral The sender domain makes no assertion about the status of the IP address.

unknown The sender domain has a syntax error in its SPF record.

error A temporary DNS error occurred while resolving the sender policy. Try again
later.

none There is no SPF record for the sender domain.

EXIT CODES
0 pass

1 fail

2 softfail

3 neutral

4 unknown

5 error

6 none

EXAMPLES

spfquery -f test_data
echo "127.0.0.1 user AT example.com helohost.example.com" | spfquery -f -
