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.
