I rent a server couple of month ago, but i never managed to configure correclty postfix.
I explain, i have 4 domains, hosted appart from the dedicaced domain and i want to recieve/send mail to my mail client (thunderbird).
Right now, the only thing which is working is the
mail() working (which is sending mail via postfix).
I'm well aware that i need to install + setup roundcube + changing the "mx" (redirecting the IP to my dedicaced server)
But i can't find any comprehensive tutorial to configure postfix with my 4 domains and handle the sending / recieving process
If you can help me, thank you in advance :D
