NAME
python-policyd-spf - pure-Python Postfix policy daemon for SPF checking
VERSION
1.3
USAGE
Usage:
policyd-spf [/usr/local/etc/postfix-policyd-spf-python/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 7208 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 configu‐
ration file cannot be found. These options can be changed by changing
the installed configuration files or through giving a path to an alter‐
nate configuration file.
Additionally, different configurations can be provided on a per user
basis. This man page describes setup and user of per user (mail recip‐
ient) 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 configura‐
tion file with the setting "Per_User". The value of the setting gives
the type and location of the per-user configuration information. Cur‐
rently 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 con‐
figurations are used when recipient information is not available, warn‐
ings 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,/usr/local/etc/postfix-policyd-spf-python/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|PermEr‐
ror_reject=False|HELO_reject=SPF_Not_Pass|defaultSeedOnly=1|debu‐
gLevel=5|skip_addresses=127.0.0.0/8,::ffff:127.0.0.0//104,::1//128|Tem‐
pError_Defer=False strict@example.com,PermEr‐
ror_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.
