Problem when I send a mail


When I send a mail with roundcube from my computer I find this message
on my maillog :

UNKNOWN[]_ is my box IP

My computer is in the same lan than my mailserver (home network).

I think I have a bad configuration somewhere, postfix or server network.

I takes any sugsestion.

This is fairly normal. It just means that postfix can't figure out the name of the connecting box by resolution or host look-up.

postfix does not use /etc/hosts.
postfix uses DNS, you should configure DNS server on your machine.
