NAME

       Mail::MtPolicyd::Plugin::SPF - mtpolicyd plugin to apply SPF checks

VERSION

       version 2.05

DESCRIPTION

       This plugin applies Sender Policy Framework(SPF) checks.

       Checks are implemented using the Mail::SPF perl module.

       Actions based on the SPF result can be applied for:

       pass (pass_mode, default: passive)
       softfail (softfail_mode, default: passive)
       fail (fail_mode, default: reject)
       temperror (temperror_mode, default: defer)
       permerror (permerror_mode, default: reject)

       For status 'neutral' no action or score is applied.

PARAMETERS

       (uc_)enabled (default: on)
           Enable/disable the plugin.

       (uc_)pass_mode (default: passive)
           How to behave if the SPF checks passed successfully:

           passive
               Just apply score. Do not return an action.

           accept, dunno
               Will return an 'dunno' action.

       pass_score (default: empty)
           Score to apply when the sender has been successfully checked against SPF.

       (uc_)softfail_mode (default: passive)
           How to behave if the SPF checks returned a softfail status.

           passive
               Just apply score. Do not return an action.

           accept, dunno
               Will return an 'dunno' action.

           reject
               Return an reject action.

       softfail_score (default: empty)
           Score to apply when the SPF check returns an softfail status.

       (uc_)fail_mode (default: reject)
           reject
               Return an reject action.

           passive
               Just apply score and do not return an action.

       temperror_mode (default: defer)
           Action to apply on a temperror SPF result.

           Possible values: passive, dunno, defer, reject

       temperror_score (default: empty)
           Score to apply on a temperror SPF result.

           By default no score is applied.

       permerror_mode (default: reject)
           Action to apply on a permerror SPF result.

           Possible values: passive, dunno, defer, reject

       permerror_score (default: empty)
           Score to apply on a permerror SPF result.

           By default no score is applied.

       reject_message (default: )
           If fail_mode is set to 'reject' this message is used in the reject.

           The following pattern will be replaced in the string:

           %LOCAL_EXPL%
               Will be replaced with a (local) explanation of the check result.

           %AUTH_EXPL%
               Will be replaced with a URL to the explanation of the result.

               This URL could be configured with 'default_authority_explanation'.

       fail_score (default: empty)
           Score to apply if the sender failed the SPF checks.

       default_authority_explanation (default: See http://www.%{d}/why/id=%{S};ip=%{I};r=%{R})
           String to return as an URL pointing to an explanation of the SPF check result.

           See Mail::SPF::Server for details.

       hostname (default: empty)
           An hostname to show in the default_authority_explanation as generating server.

       whitelist (default: '')
           A comma separated list of IP addresses to skip.

       check_helo (default: "on")
           Set to 'off' to disable SPF check on helo.

       max_dns_interactive_terms (default: 10)
           Maximum number of terms using DNS lookup in a SPF record to evaluate.

           Exceeding this limit will cause a permanent error as specified by RFC7208.

           The default of 10 is also specified in by RFC7208.

       max_name_lookups_per_term (default: 10)
           Maximum number of DNS lookups per SPF term.

       max_void_dns_lookups (default: 2)
           Maximum number of void DNS lookups.

EXAMPLE

         <Plugin spf>
           module = "SPF"
           pass_mode = passive
           pass_score = -10
           fail_mode = reject
           #fail_score = 10
         </Plugin>
