I am confused over the placement of the ! to exclude hosts
for a whitelist (to exempt the IPs in the host list)
I have:
#check for rdns - if no PTR record, deny
deny message = We do not accept messages from hosts without reverse DNS
$sender_host_address
!hosts = /etc/popb4smtp : cdb;/etc/whitelist-rdns.cdb
log_message = No reverse DNS $sender_host_address
condition = ${if eq{$sender_host_name}{}{true}{false}
I am confused if the hosts should read instead:
hosts = !/etc/popb4smtp : !cdb;/etc/whitelist-rnd.cdb
The reason I ask is that I had rejections from IPs which were/are in the
whitelist.
So I am unsure of the cdb read failed, or the syntax is incorrect in the hosts=
Thanks!
