Mail::SpamAssassin::Plugin::SPFUser)Contributed Perl DocumentMail::SpamAssassin::Plugin::SPF(3pm)
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.
has_check_for_spf_errors
Adds capability check for "if can()" for check_for_spf_permerror,
check_for_spf_temperror, check_for_spf_helo_permerror and check_for_spf_helo_permerror
