Look at the email messages you sent between your vm2 and vm3 in lab 4a. Notice that each is addressed from root on whichever machine sent it.
On vm2 onlyboth machines, edit /etc/postfix/main.cf and change the '''myorigin''' parameter from '''$myhostname''' to '''$mydomain'''. Restart postfix and send emails between the machines again. When sending from vm3 to vm2, the sender address will still be root@vm3.yourdomain.org, but when sending from vm2 to vm3 the The sender address should now read root@yourdomain.org.
