Well, the DNS based list is based on the IP sending the mail AFAIK (no
slash). I use "sender_domain = !+local_domains" to not tag mails sent by
my server, but it's not mandatory at all. So you can use the variable
$dnslist_text to check if it is incoming from Kenya, and then block it
at whatever step you wish with a condition statement.
like
deny
dnslists = country-rirdata.dnsiplists.completewhois.com
condition = ${if match {$dnslist_text}{\NKE\N} {yes}{no}}
