Recently I switched from shared web hosting to DigitalOcean VPS where I have Debian GNU/Linux 8 (jessie) running. In the web hosting I had the option to forward all emails (*@domain.com -- anything as an alias) to be forwarded to my Gmail address.
I have read a few articles on how to accomplish this with Exim, but some of them seem outdated and I am still kinda lost. How can I accomplish this?
