hi-
i've become accustomed to seeing log passages like this:
>grep -iF '[142.4.19.85]:52366' mail.log
Dec 16 09:41:09 mta1 postfix/postscreen[27678]: CONNECT from

but sometimes, the DNSBL rank seems to be absent:
>grep -iF '[104.47.32.71]:33498' mail.log.1

is this expected? if not, how can i determine why it's happening?
