I use this one:

# Dial-up/cable/dsl check

dialup_acl:

   accept  condition      = ${if def:acl_c3}
           condition      = $acl_c3

   deny    condition      = ${if def:acl_c3}

   accept  acl            = raw_dialup_acl
           set acl_c3     = yes

   deny    set acl_c3     = no

raw_dialup_acl:

# Known not dialup hosts

   deny    hosts         = *.amazon.com:*.yahoo.com:*.hotmail.com

# Get hostname on acl_c4

   warn    condition     = ${if !def:acl_c4}
           condition     = ${if eq {$sender_host_name}{}}
           set acl_c4    = ${lookup 
dnsdb{defer_never,ptr=$sender_host_address}\
                            {${lc:$value}}{}}

   warn    condition     = ${if !def:acl_c4}
           set acl_c4    = ${lc:$sender_host_name}

   accept  condition     = ${if eq {$acl_c4}{}}

   accept  condition     = ${if match {$acl_c4}\
                           {\N\b[a-z]*?(\d{1,3}[\.\-x]\d{1,3}|\
([a-z]?dsl(am)?|dhcp|tnt|ipt|pool|nas|cvx|leased|\
slip|user|subscriber|d[iu]p|modem(cable)?|ppp(oe)?|\
dyn(amic)?|dial(up|in)?|cust(omers?)?|(end)?users?|\
d?cliente?)\d*?)\b\N}}

   accept  condition     = ${if match {$acl_c4}{\N\d{5,}\N}}

   accept  condition     = ${if match {$acl_c4}\
{(comcast\.net|ips\.sarenet\.es|prod-empresarial\.com\.mx|\

   accept  dnslists      = dnsbl.sorbs.net=127.0.0.10:\
dialup.blacklist.jippg.org:dynablock.easynet.nl

deny
