Answer the following Exploration questions in your lab book.:
→Completing the Lab
Upon completion of this lab you should have postfix mail servers running on two machines, and starting automatically when they do. These servers must have sent email both ways between each other (from VM 2 to VM 3, and from VM 3 to VM 2), and to your seneca email.
#What did changing the relay_domains parameter do?
#What firewall rule or rules, if any, did you have to enter so that email between your VMs would work?
#What is the meaning of the square brackets surrounding the IP address in the examples?
#What were the results of sending email between the VMs? Show log segments to verify your answers.
