Well it can do a lot and even act authoritatively for some stuff,
it call itself a caching DNS server. Note i use it, but it can
much more than i ever asked it for. Which is true for all my
program use cases btw, even including vim(1) i use for so long.
(In the meantime i even use it to deliver DHCP in some network
namespaces, namely vm, and there i have the problem that it does
not act authoritatively for IPv6 even though it did assign an IPv4
address, which is a problem since by default many
things-to-be-resolved send out A and AAAA and only one is
answered, the other is forwarded, which is a nuisance .. but 'got
no answer a couple of months back .. IPv6 is disabled here, i had
to reread the RFCs and learn it anew.)
I do use _rbl_ stuff with zen.spamhaus.org and dnsbl.sorbs.net and
sometimes it even hits? But i am not a postfix configuration
expert and may definitely falsely understand what you mean.
