NAME

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

VERSION

version 2.02

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)

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.

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.
