Mail::SpamAssassin::PlUser:Contributed Perl Mail::SpamAssassin::Plugin::SPF(3)

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
       whitelist_from_spf user AT example.com
           Works similarly to whitelist_from, except that in addition to
           matching a sender address, a check against the domain's SPF record
           must pass.  The first parameter is an address to whitelist, and the
           second is a string to match the relay's rDNS.
           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 AT example.com fred AT example.com
             whitelist_from_spf *@example.com
       def_whitelist_from_spf user AT example.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.
ADMINISTRATOR OPTIONS
       spf_timeout n       (default: 5)
           How many seconds to wait for an SPF query to complete, before
           scanning continues without the SPF result. A numeric value is
           optionally suffixed by a time unit (s, m, h, d, w, indicating
           seconds (default), minutes, hours, days, weeks).
       do_not_use_mail_spf (0|1)          (default: 0)
           By default the plugin will try to use the Mail::SPF module for SPF
           checks if it can be loaded.  If Mail::SPF cannot be used the plugin
           will fall back to using the legacy Mail::SPF::Query module if it
           can be loaded.
           Use this option to stop the plugin from using Mail::SPF and cause
           it to try to use Mail::SPF::Query instead.
       do_not_use_mail_spf_query (0|1)    (default: 0)
           As above, but instead stop the plugin from trying to use
           Mail::SPF::Query and cause it to only try to use Mail::SPF.
       ignore_received_spf_header (0|1)   (default: 0)
           By default, to avoid unnecessary DNS lookups, the plugin will try
           to use the SPF results found in any "Received-SPF" headers it finds
           in the message that could only have been added by an internal
           relay.
           Set this option to 1 to ignore any "Received-SPF" headers present
           and to have the plugin perform the SPF check itself.
           Note that unless the plugin finds an "identity=helo", or some
           unsupported identity, it will assume that the result is a mfrom SPF
           check result.  The only identities supported are "mfrom",
           "mailfrom" and "helo".
       use_newest_received_spf_header (0|1)    (default: 0)
           By default, when using "Received-SPF" headers, the plugin will
           attempt to use the oldest (bottom most) "Received-SPF" headers,
           that were added by internal relays, that it can parse results from
           since they are the most likely to be accurate.  This is done so
           that if you have an incoming mail setup where one of your primary
           MXes doesn't know about a secondary MX (or your MXes don't know
           about some sort of forwarding relay that SA considers
           trusted+internal) but SA is aware of the actual domain boundary
           (internal_networks setting) SA will use the results that are most
           accurate.
           Use this option to start with the newest (top most) "Received-SPF"
           headers, working downwards until results are successfully parsed.
