Users can control their own mail delivery by specifying destinations in a file called .forward in their home directories. The syntax of these files is the same as system aliases, except that the lookup key and colon are not present.
I will illustrate an example here:
Assume that you need to forward all the mails which come to the sysadmin account to an another account. Enter the following commands:
su - sysadmin touch .forward
Then open the .forward file
vi .forward
Add the following code:
fossedu@example.com
Remember to use email address which exists in this exercise.
Now send a mail to sysadmin and mail should come to fossedu@example.com
