deny condition = ${if match {$sender_host_name}{<your regex>}{1}{0}}
but note that there are restrictions on $sender_host_name - it only
gets set when a full reverse-then-forward DNS lookup succeeds and
matches. You might need to do some trickery with dnsdb if you need
something other than this behaviour.
