SPFD(1) User Contributed Perl Documentation SPFD(1)
NAME
spfd - simple forking daemon to provide SPF query services
VERSION
2006-02-07
SYNOPSIS
spfd --port port [--set-user uid|username] [--set-group gid|groupname]
spfd --socket filename [--socket-user uid|username] [--socket-group gid|groupname] [--socket-perms octal-perms] [--set-user uid|username]
[--set-group gid|groupname]
spfd --help
DESCRIPTION
spfd is a simple forking Sender Policy Framework (SPF) query proxy server. spfd receives and answers SPF query requests on a TCP/IP or
UNIX domain socket.
The --port form listens on a TCP/IP socket on the specified port. The default port is 5970.
The --socket form listens on a UNIX domain socket that is created with the specified filename. The socket can be assigned specific user
and group ownership with the --socket-user and --socket-group options, and specific filesystem permissions with the --socket-perms option.
Generally, spfd can be instructed with the --set-user and --set-group options to drop root privileges and change to another user and group
before it starts listening for requests.
The --help form prints usage information for spfd.
REQUEST
A request consists of a series of lines delimited by x0A (LF) characters (or whatever your system considers a newline). Each line must be
of the form key=value, where the following keys are required:
ip The sender IP address.
sender
The envelope sender address (from the SMTP "MAIL FROM" command).
helo
The envelope sender hostname (from the SMTP "HELO" command).
RESPONSE
spfd responds to query requests with similar series of lines of the form key=value. The most important response keys are:
result
The result of the SPF query:
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.
smtp_comment
The text that should be included in the receiver's SMTP response.
header_comment
The text that should be included as a comment in the message's "Received-SPF:" header.
spf_record
The SPF record of the envelope sender domain.
For the description of other response keys see Mail::SPF::Query.
For more information on SPF see <http://www.openspf.org>.
EXAMPLE
A running spfd could be tested using the "netcat" utility like this:
$ echo -e "ip=11.22.33.44
sender=user@pobox.com
helo=spammer.example.net
" | nc localhost 5970
result=neutral
smtp_comment=Please see http://spf.pobox.com/why.html?sender=user%40pobox.com&ip=11.22.33.44&receiver=localhost
header_comment=localhost: 11.22.33.44 is neither permitted nor denied by domain of user@pobox.com
guess=neutral
smtp_guess=
header_guess=
guess_tf=neutral
smtp_tf=
header_tf=
spf_record=v=spf1 ?all
