NAME

       python-policyd-spf - pure-Python Postfix policy daemon for SPF checking

VERSION

       1.0

USAGE

       Usage:
         policyd-spf [/etc/policyd-spf/policyd-spf.conf]

OTHER DOCUMENTATION

       This documentation assumes you have read Postfix's README_FILES/ SMTPD_POLICY_README and
       are generally familiar with Sender Policy Framework (SPF).  See RFC 4408 for details.

       man 1 policyd-spf provides general operation documentation for this package.

       See man 5 policyd-spf.conf for configuration file information.

SYNOPSIS

       python-policyd-spf operates with a default installed configuration file and set of default
       configuration options that are used if the configuration file cannot be found.  These
       options can be changed by changing the installed configuration files or through giving a
       path to an alternate configuration file.

       Additionally, different configurations can be provided on a per user basis.  This man page
       describes setup and user of per user (mail recipient) configurations.  Currently these
       configurations can either be stored in a text file or a Berkeley DB (libdb) datase.  If
       there is sufficient interest, other data storage methods may be supported in the future.

DESCRIPTION

       Use of per-user configuration is defined in the application configuration file with the
       setting "Per_User".  The value of the setting gives the type and location of the per-user
       configuration information.  Currently supported types are text and bsddb.  User is defined
       an email address of a recipient of the message.

       All options available at the application level (See man 5 policyd-spf.conf) can be
       adjusted on a per-user basis.  Per-user checks can only be done as part of
       smtpd_recipient_restrictions.  Per-user actions are not possible at other stages of the
       SMTP dialogue.  The user is not yet known for smtpd_client_restrictions,
       smtpd_helo_restrictions, or smtpd_sender_restrictions.  If used during
       smtpd_data_restrictions or smtpd_end_of_data_restrictions, the entire message will be
       available only if the message was only to a single recipient.  If per-user configurations
       are used when recipient information is not available, warnings will be logged and the per-
       user information will be ignored.

       In addition to specifying individual users, regular expression matching is also available,
       but may have performance implications since the entire user table has to be traversed for
       each message recipient.

OPTIONS

Text Per-User Configuration File

       The text file option is useful for testing and when only a small number of users require
       per-user configurations.  It is specified in the main configuration file:

       "Per_User = text,/etc/pypolicyd-spf/userconf"

       Lines beginning with "#" are treated as comments and ignored.  The location of the file is
       determined by the system administrator. No default file is provided in or installed by the
       package.

       The configuration of the file is a comma separated combination of user and configuration
       information, with one line per user's configuration information (NOTE: due to man page
       formating requirements, these lines are wrapped - in the config file, it must be one line
       per user):

       postmaster@example.com,Mail_From_reject=No_Check|PermError_reject=False|HELO_reject=SPF_Not_Pass|defaultSeedOnly=1|debugLevel=5|skip_addresses=127.0.0.0/8,::ffff:127.0.0.0//104,::1//128|TempError_Defer=False
       strict@example.com,PermError_rejec=True|HELO_reject=SPF_Not_Pass|TempError_Defer=True

       It is not necessary to specify all configuration parameters for each user, only those that
       are different than the overall configuration need to be specified.

       If the specified per user configuration file is missing, an error is logged and the global
       configuration is used instead.
