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 example: "--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.
