policyd-spf.peruser man page
policyd-spf — policyd-spf python per-user configuration
This documentation assumes you have read Postfix's README_FILES/ SMTPD_POLICY_README and are generally familiar with Sender Policy Framework (SPF). See RFC 7208 for details.
man 1 policyd-spf provides general operation documentation for this package.
See man 5 policyd-spf.conf for configuration file information.
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 only be stored in a text file. If there is sufficient interest, other data storage methods may be supported in the future.
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 is text. User is defined an email address of a recipient of the message.
Most 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.
The following options cannot be modified on a per user basis: Lookup_Time, Header_Type, Hide_Receiver, Authserv_Id, Prospective, debugLevel, and Mock.
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.
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 formatting requirements, these lines may be wrapped in your pager - in the config file, it must be one line per user):
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.
