Mail::SpamAssassin::PlUser:Contributed PMail::SpamAssassin::Plugin::DNSEval(3)

NAME
       DNSEVAL - look up URLs against DNS blocklists

SYNOPSIS
	loadplugin Mail::SpamAssassin::Plugin::DNSEval

	rbl_headers EnvelopeFrom,Reply-To,Disposition-Notification-To
	header	   RBL_IP    eval:check_rbl_headers('rbl', 'rbl.example.com.', '127.0.0.2')
	describe   RBL_IP    From address associated with spam domains
	tflags	   RBL_IP    net
	reuse	   RBL_IP

	Supported extra	tflags from SpamAssassin 3.4.3:
	 domains_only -	only non-IP-address "host" components are queried
	 ips_only - only IP addresses as the "host" component will be queried

DESCRIPTION
       The DNSEval plugin queries dns to see if	a domain or an ip address
       present on one of email's headers is on a particular rbl.

USER PREFERENCES
       The following options can be used in both site-wide ("local.cf")	and
       user-specific ("user_prefs") configuration files	to customize how
       SpamAssassin handles incoming email messages.

       rbl_headers
	    This option	tells SpamAssassin in which headers to check for content
	    used to query the specified	rbl.
	    If on the headers content there is an email	address, an ip address
	    or a domain	name, it will be checked on the	specified rbl.
	    The	configuration option can be overridden by passing an headers list as
	    last parameter to check_rbl_headers.
	    The	default	headers	checked	are:

       o   EnvelopeFrom

       o   Reply-To

       o   Disposition-Notification-To

       o   X-WebmailclientIP

       o   X-Source-IP

       check_rbl_from_domain
	   This	checks all the from addrs domain names as an alternate to
	   check_rbl_from_host.	 As of v3.4.1, it has been improved to include
	   a subtest for a specific octet.

       check_rbl_ns_from
	   This	checks the dns server of the from addrs	domain name.  It is
	   possible to include a subtest for a specific	octet.

       check_rbl_rcvd
	   This	checks all received headers domains or ip addresses against a
	   specific rbl.  It is	possible to include a subtest for a specific
	   octet.
