I dunno about cf files, but I've done it with mc files. Add the
following at the end of the .mc file:
LOCAL_RULESETS
SLocal_check_relay
# Deny addresses which fail reverse-lookup
R[ $+ ] $| $+ $#error $@ 5.7.1 $: "550 Access denied, your host failed a reverse-lookup"
Note: theres a <TAB> before $#error.
Cheers.
