Check for DNS recursion restrictions
About the recursion, I would just edit your own /etc/named.conf file and add this line:
allow-recursion { localnets; };
Somewhere in the
options {
container.
It might look like this then:
// generated by named-bootconf.pl options { directory "/var/named"; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below. Previous versions of BIND always asked * questions using port 53, but BIND 8.1 uses an unprivileged * port by default. */ // query-source address * port 53; allow-transfer { none; }; allow-recursion { localnets; }; };
Don’t forget to restart named.
For exim, edit your /etc/exim.conf and look under log_selector.
It should contain these settings:
log_selector = \ +arguments \ +subject \ +received_recipients \ +delivery_size \ +sender_on_delivery \ +received_sender \ +smtp_confirmation \ +smtp_incomplete_transaction \
Most are already present in your exim.conf, just add the ones that are missing.
After that, restart exim.
Mostly if you click on the notices CSF gives you, it will show you the solution how to fix it.
