You should not use public dns servers to query dnsbls as they are likely
blocked due to excessive query volume at the dnsbl. Install and use a
local resolver like unbound, knot, bind and use nameserver 127.0.0.1 in
/etc/resolv.conf
in addition to this, you can whitelist outlook's IP ranges at postscreen
level, as they "likely" aren't what postscreen is supposed to stop - bots.
