Hey,
i installed the filter "filter-dnsbl" from here
(http://imperialat.at/dev/filter-dnsbl/) and now i want to add it to my
config. However, i have to admit i have no idea how to do that? In what
"phase" should i put this filter? I looked around but i found a couple
of outdated blog posts on filters, but nothing current. I also read thru
here
(https://github.com/openbsd/src/blob/master/usr.sbin/smtpd/smtpd-filters.7),
but i found nothing.
If someone of you has a working example on how to use that filter, could
you please be so kind and send it to me?
Thanks so much and greetings
Leo
