Changing myorigin on vm2 only.
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 both machinesvm2 only, edit /etc/postfix/main.cf and change the '''myorigin''' parameter from '''$myhostname''' to '''$mydomain'''. Restart postfix and send emails between the machines again. The When sending from vm3 to vm2, the sender address will still be root@vm3.yourdomain.org, but when sending from vm2 to vm3 the sender address should now read root@yourdomain.org.
