I am sure it is a dumb question, but I want to change the sender of mails sended by my Linux server (centos 5). All mails sent to user "dev" are forwarded via a /home/dev/.forward file, with this sender : firstname.lastname@example.org.
host.mydomain.fr is the hostname of this server, but it's an internal server and it does not even have a public IP. How to have a sender like email@example.com? I try to change the "official domain name" (line begining by "Dj" but it change nothing).
