Hi,

seems EFA tries to connect to serveral DNS server
192.xx.xx.xx:44074 85.xx.xx.xx:53
Does https://wiki.efa-project.org/doku.php?id=firewall_ports missing the UDP out 53 DNS queries?
Why does EFA send queries to serveral internet addresses? Kind of spam check?

I updated the wiki page, UDP 53 out is also needed.

DNS RBL checks use a simple dns query, so for RBL (spamhaus etc) to work correctly the system should be able to send out DNS query's to those RBL servers.
