How to forward email from your VPS to an external email provider

I use Linode to host my domains. I had a need to have an official looking email, and found this post by Jesse Lau. However he is missing a crucial line which I found in this Linode forum post:

virtual_alias_domains = ducklington.org

So the entire correct recipe is:

  1. Install postfix
    apt-get update
    apt-get upgrade
    apt-get install postfix
  2. /etc/postfix/main.cf download and edit
    virtual_alias_domains = ducklington.org
    virtual_alias_maps = hash:/etc/postfix/virtual
  3. /etc/postfix/virtual
    jim@ducklington.org jim@gmail.com
    ted@ducklington.org ted@gmail.com
  4. postmap /etc/postfix/virtual to build database
  5. /etc/init.d/postfix reload

Some of the chat from the helpful people in the Linode IRC channel may prove of use:
