Hi, My server is a PHP web server + BIND9 + Postfix + Dovecot. It is on a private network using port forwarding. There seems to be a lot of advice on the Internet... The only solution that works for me is to add a line like this one: "192.168.10.104 hostname.example.tld hostname" to /etc/hosts. I used the IP of the server not the public IP that hits my router. Does this sound right? Thanks!! --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.phxlinux.org To subscribe, unsubscribe, or to change your mail settings: https://lists.phxlinux.org/mailman/listinfo/plug-discuss
