       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 stan-
       dard 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 re-
           sult (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 example: "--override example.org='v=spf1 -all' --over-
           ride '*.example.net'='v=spf1 a mx -all' --fallback exam-
           ple.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
