Mail::SpamAssassin::Plugin::DomUsereContributed Perl DMail::SpamAssassin::Plugin::DomainKeys(3pm)
NAME
Mail::SpamAssassin::Plugin::DomainKeys - perform DomainKeys verification tests
SYNOPSIS
loadplugin Mail::SpamAssassin::Plugin::DomainKeys [/path/to/DomainKeys.pm]
Signature:
header DK_SIGNED eval:check_domainkeys_signed()
header DK_VERIFIED eval:check_domainkeys_verified()
Policy:
Note that DK policy record is only fetched if DK_VERIFIED is
false to save a signing domain from unnecessary DNS queries,
as recommended (SHOULD) by draft-delany-domainkeys-base.
Rules DK_POLICY_* should preferably not be relied upon when
DK_VERIFIED is true, although they will return false in current
implementation when a policy record is not fetched, except for
DK_POLICY_TESTING, which is true if t=y appears in a public key
record OR in a policy record (when available).
header DK_POLICY_TESTING eval:check_domainkeys_testing()
header DK_POLICY_SIGNSOME eval:check_domainkeys_signsome()
header DK_POLICY_SIGNALL eval:check_domainkeys_signall()
Whitelisting based on verified signature:
header USER_IN_DK_WHITELIST eval:check_for_dk_whitelist_from()
header USER_IN_DEF_DK_WL eval:check_for_def_dk_whitelist_from()
DESCRIPTION
This is the DomainKeys plugin and it needs lots more documentation.
Note that if the "Mail::SpamAssassin::Plugin::DKIM" plugin is installed with "Mail::DKIM"
version 0.20 or later, that plugin will also perform Domain Key lookups on DomainKey-
Signature headers, in which case this plugin is redundant.
Here is author's note from module "Mail::DomainKeys" version 1.0:
THIS MODULE IS OFFICIALLY UNSUPPORTED.
Please move on to DKIM like a responsible Internet user. I have.
I will leave this module here on CPAN for a while, just in case someone
has grown to depend on it. It is apparent that DK will not be the way
of the future. Thus, it is time to put this module to ground before it
causes any further harm.
Thanks for your support,
Anthony
USER SETTINGS
whitelist_from_dk add AT ress.com [signing domain name]
Use this to supplement the whitelist_from addresses with a check to make sure the
message has been signed by a DomainKeys signature that can be verified against the
From: domain's DomainKeys public key.
In order to support signing domain names that differ from the address domain name,
only one whitelist entry is allowed per line, exactly like "whitelist_from_rcvd".
Multiple "whitelist_from_dk" lines are allowed. File-glob style meta characters are
allowed for the From: address, just like with "whitelist_from_rcvd". The optional
signing domain name parameter must match from the right-most side, also like in
"whitelist_from_rcvd".
If no signing domain name 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 a DomainKeys check to be made, network tests must be
enabled.
Examples:
whitelist_from_dk joe AT example.com
whitelist_from_dk *@corp.example.com
whitelist_from_dk bob AT it.net example.net
whitelist_from_dk *@eng.example.net example.net
def_whitelist_from_dk add AT ress.com [signing domain name]
Same as "whitelist_from_dk", 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
domainkeys_timeout n (default: 5)
How many seconds to wait for a DomainKeys query to complete, before scanning continues
without the DomainKeys result.
