I've recently bought a domain from 123-Reg and have set up the email forwarding so that anyone who emails email@example.com ends up getting through to my personal Gmail account. Now, I want to set it up so that when I reply the reply reads from firstname.lastname@example.org as opposed to email@example.com. Problem is I have absolutely no idea how to do this though!? Is it something I have to set up in Gmail, or is it something I do in the 123-Reg control panel? Unfortunately 123-Reg's help leaves a little to be desired on this topic! Any advice would be greatly appreciated!
