* Regex fix, checkip argument & updated tld list This patch include 3 fixes: 1) The plugin could match invalid URIs, eg. "www..example.com", which resulted in fatal plugin error, sending the incoming email directly into queue without any further scan. The regex has been fixed. 2) Some URIBLs trigger positive on any ip-address. Added new plugin argument: checkip [yes|no]. 3) Updating the TLD list. Co-authored-by: mufus <hello@mufus.com>

=head1 NAME
|
|
|
|
uribl - URIBL blocking plugin for qpsmtpd
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This plugin implements DNSBL lookups for URIs found in spam, such as that
|
|
implemented by SURBL (see E<lt>http://surbl.org/E<gt>). Incoming messages are
|
|
scanned for URIs, which are then checked against one or more URIBLs in a
|
|
fashion similar to DNSBL systems.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
To enable the plugin, add it to I<~qpsmtpd/config/plugins>. The list of
|
|
URIBLs to check should be placed in I<uribl_zones> in the config directory
|
|
(typically I<~qpsmtpd/config>).
|
|
|
|
The format of the I<uribl_zones> file is a list of URIBL DNS zones, one per
|
|
line, consisting of one or more columns separated by whitespace. The first
|
|
column (the only mandatoy one) should consist of the URIBL zone.
|
|
|
|
The second column may contain a comma-delimited list of integers selecting
|
|
mask values to be applied to the A record(s) returned from a URIBL. This
|
|
enables the use of composite DNSBLs, such as multi.surbl.org, where several
|
|
lists are combined so they may be accessed with a single query; any returns
|
|
are checked against the mask of lists you're interested in. If unspecified,
|
|
or if a negative number is given, all lists in a composite URIBL will be
|
|
checked. URIBL operators prefer that you use the composite lists to reduce
|
|
their own query load, and it's more efficient for qpsmtpd as well.
|
|
|
|
The third column specifies an action, which overrides the default action
|
|
configured with the I<action> setting discussed below.
|
|
|
|
For example:
|
|
|
|
=over 4
|
|
|
|
multi.surbl.org 2,8 deny
|
|
ob.surbl.org 1 add-header
|
|
|
|
=back
|
|
|
|
You may specify the following config option(s) in the I<qpsmtpd/config> file:
|
|
|
|
=over 4
|
|
|
|
=item action
|
|
|
|
Specifies what to do when a URI is matched in a URIBL. Available options are
|
|
I<add-header> (the default) I<deny> and I<denysoft>. If set to add-header, an
|
|
X-URIBL-Match: header will be added explaining the URIBL entry found. If set
|
|
to 'deny,' the delivery will be declined with a hard failure. If set to
|
|
denysoft, the delivery will be soft failed (this is probably not a good idea.)
|
|
|
|
=item timeout
|
|
|
|
Timeout for DNS requests, in seconds. The default is 30 seconds. DNS
|
|
requests are issued asynchronously and in parallel for all hosts found
|
|
in URIs in the mail; the same timeout will apply to each; see the
|
|
Net::DNS documentation for details.
|
|
|
|
=item scan-headers
|
|
|
|
If set true, any headers found in the URIs will be checked as well. Disabled
|
|
by default.
|
|
|
|
=item checkip [yes|no]
|
|
|
|
Specifies whether ip-addresses should be searched for or not. Some URIBLs
|
|
only allows domain names and triggers positive on any ip-address.
|
|
Default value: yes.
|
|
|
|
=back
|
|
|
|
=head1 CAUTIONS
|
|
|
|
When used in I<deny> or I<denysoft> mode, a URIBL check can block not
|
|
only the original spam containing a listed URI, but mail unintentionally
|
|
carrying that URI, such as forwarded complaints. The uribl checks should
|
|
only be used in these modes if you know what you're doing.
|
|
|
|
The URI scanner used by the uribl plugin is quite aggressive, and attempts to
|
|
detect all forms of URIs supported by typical MUAs (even those that lack a
|
|
protocol specification, for example.) However, it does not attempt to detect
|
|
URIs that have been mangled beyond programmatic reconstruction. Even so, it
|
|
may issue spurious lookups on unintended URIs, especially those in non-text
|
|
sections of the mail.
