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.
