[exim] using $dnslist to fight spam in Exim4.60

Hello everyone!

I am trying to grok spam fighting with ACLs. Please note that I am using a
debian based system but
I am explicitly asking on the "upstream" list. I will translate any advice
provided to my debian specific
configuration file.

In my spamassassin header called X-Spam-Report there is a line:

RBL: SORBS: sent directly from dynamic IP address [82.121.16.205 listed in
dnsbl.sorbs.net]


I understand this to mean "Realtime Blacklist" from sorbs.net. I would like
to incorporate this list
directly into my exim4 conf file. I placed this stanza there:

deny            message = Access denied - $sender_host_address\
                          listed by $dnslist_domain\n$dnslist_text
                dnslists = dnsbl.sorbs.net

But above it is another stanza that perhaps already includes Sorbs;

  # Check against classic DNS "black" lists (DNSBLs) which list
  # sender IP addresses
  .ifdef CHECK_RCPT_IP_DNSBLS
  warn
    message = X-Warning: $sender_host_address is listed at $dnslist_domain
($dnslist_value: $dnslist_text)
    log_message = $sender_host_address is listed at $dnslist_domain
($dnslist_value: $dnslist_text)
    dnslists = CHECK_RCPT_IP_DNSBLS
  .endif

Is my addition of the Sorbs list redundant?

Thank you,

Jeremiah
