how to change email id in ubuntu server

By default, any email sent by system is sent to root@hostname. So critical server errors, log errors, corn jobs alerts e.t.c all are sent to this default email address. To change it to different appropriate email id, we can do this by two ways.

By updating email aliases file:

For this example, lets set email to

Step 1 : edit /etc/aliases file 

$ vi /etc/aliases

Add email ids at the bottom of the file.


To add multiple email ids, we can simply separate them by comma.

postmaster:, is second email id 

Step 2: Run the aliases command, to compile aliases file. 

$ newaliases

Step 3: Restart postfix server.

service postfix restart

Second way:

We can simply create .forward file to the folder root and add email address there.

$ vi /root/.forward

Restart postfix server
$ service postfix restart.
