The forwarding section is one of the easiest and most useful sections in the entire cpanel. Once you have set up an email account on your domain from within cpanel, you will often wish to forward it to another account. Perhaps your business is just starting up and you have very little mail coming in yet, but you always check your personal mail twice a day. You could set up forwarding from an account on your newly acquired domain and send it to your personal account. To do that go to the button in the lower center of the page that says Add Forwarder.
Step 1) Enter the email address from your new domain that you want forwarded and adjust the domain drop down to the correct domain (there will not be a choice unless you have add on domains in your account).
Step 2) Enter the full email address that you want it forwarded to.
Step 3) Click the add forwarder button at the bottom.
The advance settings here are not useful unless you need to send your email to a specific program installed on the server in which case you want the pipe to a program setting.
