Hi !!

Just some corrections to a better use of dns lookups

better user dnslists = sbl.spamhaus.org : \
                       relays.ordb.org : \
                       dnsbl.sorbs.net=127.0.0.5


dnsbl.sorbs.net=127.0.0.5 it's the same as smtp.dnsbl.sorbs.net, but it
allows exim to cache the result and avoid one extra dns lookup.

better user dnslists = bl.spamcop.net : \
                       dnsbl.njabl.org : \
                       cbl.abuseat.org : \
               dnsbl.sorbs.net


as dnsbl.sorbs.net includes all the sorbs.net rbl's and needs only one
lookup. Also rhsbl.sorbs.net is not ip based, it's domain based, you
should use it like this

dnslists = rhsbl.sorbs.net/$sender_address_domain

Best regards ...

I feel like a fugitive from the law of averages.
