Mail::SpamAssassin::PlUusgeirn:C:oSnPtFr(i3b)uted


NAME

  Mail::SpamAssassin::Plugin::SPF - perform SPF verification tests


SYNOPSIS

    loadplugin	   Mail::SpamAssassin::Plugin::SPF


DESCRIPTION

  This plugin checks a message against Sender Policy Framework (SPF) records
  published by the domain owners in DNS to fight email address forgery and
  make it easier to identify spams.


USER SETTINGS

  spf_timeout n		  (default: 5)
      How many seconds to wait for an SPF query to complete, before scanning
      continues without the SPF result.

  whitelist_from_spf add@ress.com
      Use this to supplement the whitelist_from addresses with a check
      against the domain's SPF record. Aside from the name
      'whitelist_from_spf', the syntax is exactly the same as the syntax for
      'whitelist_from'.

      Just like whitelist_from, multiple addresses per line, separated by
      spaces, are OK. Multiple "whitelist_from_spf" lines are also OK.

      The headers checked for whitelist_from_spf addresses are the same
      headers used for SPF checks (Envelope-From, Return-Path,
      X-Envelope-From, etc).

      Since this whitelist requires an SPF check to be made network tests
      must be enabled. It is also required that your trust path be correctly
      configured.  See the section on "trusted_networks" for more info on
      trust paths.

      e.g.

	whitelist_from_spf joe@example.com fred@example.com
	whitelist_from_spf *@example.com

  def_whitelist_from_spf add@ress.com
      Same as "whitelist_from_spf", but used for the default whitelist
      entries in the SpamAssassin distribution.	 The whitelist score is
      lower, because these are often targets for spammer spoofing.
