NAME
       pyspf-milter - SPF checking filter for MTAs


SYNOPSIS
       pyspy-milter [configfile]


DESCRIPTION
       pyspf-milter implements the SPF standard for checking e-mail messages on a (mostly) per-
       domain basis.

       pyspf-milter uses the milter interface, originally distributed as part of version 8.11 of
       sendmail(8), to provide SPF checking services for mail transiting a milter-aware MTA.


OPTIONS
       See    policyd-spf.conf (5) for information about available options. With the exception of
              specifying the configuration file to use, pyspf-milter does not support command
              line option switches.


NOTES
       When using DNS timeouts be sure not to use a timeout that is larger than the timeout being
       used for interaction between sendmail and the filter.  Otherwise, the MTA could abort a
       message while waiting for a reply from the filter, which in turn is still waiting for a
       DNS reply.


EXIT STATUS
       Filter exit status codes are selected according to sysexits(3).


HISTORY
       SPF is an amalgam of several earlier proposals.  It was originally specified in RFC 4408.
       The current specification is RFC 7208.  The SPF related processing was developed for use
       with the Postfix unique policy service in the pypolicyd-spf project.  When the milter
       interface was added, the project was renamed SPF Engine.


VERSION
       This man page covers version 3.0.0 of pyspf-milter.
