title: Postfix/Dovecot setup only accepting messages to one user
body: <p>I have installed Postfix and Dovecot on my Raspberry Pi. The Pi is behind the domain <code>scubbo.org</code>. When I send email (from a GMail account, via web) to pi@scubbo.org, the mail is delivered:</p>
  
  <pre><code>pi@raspberrypi /etc/postfix $ whoami
  pi
  pi@raspberrypi /etc/postfix $ mail
  Heirloom mailx version 12.5 6/20/10.  Type ? for help.
  "/var/mail/pi": 1 message 1 new
  &gt;N  1 Jack Jackson       Sat May 24 00:06   42/1825  This was sent from gmail to pi@scubbo.org
  </code></pre>
  
  <p>But when I try the same thing to scubbo@scubbo.org, it's not delivered:</p>
  
  <pre><code>pi@raspberrypi /etc/postfix $ su - scubbo
  Password:
  scubbo@raspberrypi:~$ mail
  No mail for scubbo
  </code></pre>
  
  <p>Any ideas why? There's no special config that I can see for either:</p>
  
  <pre><code>pi@raspberrypi /etc/postfix $ grep -ir 'pi' .
  [...only results for "pipe", "recipients", etc...]
  pi@raspberrypi /etc/postfix $ grep -ir 'scubbo' .
  [...only results for the domain, not the user...]
  </code></pre>
