Bug#280484: SPF not working/enabled in exiscan patch

[Kilian Krause]

Package: exim4-daemon-heavy
Version: 4.34-6
Severity: normal

As the original exiscan (http://duncanthrax.net/exiscan-acl/) reads that
it should have native SPF in it, i wonder how come i cannot use the
config sniplet like in
http://www.tldp.org/HOWTO/Spam-Filtering-for-MX/exim-spf.html:
-(snip)-
# Query the SPF information for the sender address domain, if any,
# to see if the sending host is authorized to deliver its mail.
# If not, reject the mail.
#
deny
	message     = [SPF] $sender_host_address is not allowed to send mail \
		      from $sender_address_domain
	log_message = SPF check failed.
	spf         = fail


# Add a SPF-Received: header
# to the message
warn
	message     = $spf_received

-(snip)-


Not that the page wouldn't have warned me, but what's the rationale i
have to go thru forking an extra task (spfquery) when the exiscan-acl
should have it already in the first place?!
