Mail::SpamAssassin::Plugin::DKIM.3pm

NAME

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

SYNOPSIS

  loadplugin Mail::SpamAssassin::Plugin::DKIM [/path/to/DKIM.pm]
 
 

  full DOMAINKEY_DOMAIN eval:check_dkim_verified()
 
 

DESCRIPTION

This SpamAssassin plugin implements DKIM lookups as described by the current draft specs: draft-ietf-dkim-base-10, as well as DomainKeys lookups, as described in draft-delany-domainkeys-base-06, thanks to the support for both types of signatures by newer versions of module Mail::DKIM (0.22 or later).

It requires the "Mail::DKIM" CPAN module to operate. Many thanks to Jason Long for that module.

Note that if "Mail::DKIM" version 0.20 or later is installed, this plugin will also perform Domain Key lookups on DomainKey-Signature headers.

USER SETTINGS

whitelist_from_dkim add@ress.com [identity]

Use this to supplement the whitelist_from addresses with a check to make sure the message has been signed by a Domain Keys Identified Mail (DKIM) signature that can be verified against the From: domain's DKIM public key.

In order to support optional identities, only one whitelist entry is allowed per line, exactly like "whitelist_from_rcvd". Multiple "whitelist_from_dkim" lines are allowed. File-glob style meta characters are allowed for the From: address, just like with "whitelist_from_rcvd". The optional identity parameter must match from the right-most side, also like in "whitelist_from_rcvd".

If no identity parameter is specified the domain of the address parameter specified will be used instead.

The From: address is obtained from a signed part of the message (ie. the ``From:'' header), not from envelope data that is possible to forge.

Since this whitelist requires an DKIM check to be made, network tests must be enabled.

Examples:

   whitelist_from_dkim joe@example.com
   whitelist_from_dkim *@corp.example.com
 
 

   whitelist_from_dkim jane@example.net  example.org
   whitelist_from_dkim dick@example.net  richard@example.net
 
 

def_whitelist_from_dkim add@ress.com [identity]

Same as "whitelist_from_dkim", 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 SETTINGS

dkim_timeout n (default: 5)

How many seconds to wait for a DKIM query to complete, before scanning continues without the DKIM result.
