For Dovecot to work, you will need to do the following:

1) Create configuration in #{etc}

2) If required by the configuration above, create a dovecot user and group

3) possibly create a launchd item in /Library/LaunchDaemons/org.dovecot.plist, like so:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>org.dovecot</string>
        <key>ProgramArguments</key>
        <array>
                <string>#{sbin}/dovecot</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
</dict>
</plist>

4) start the server using: sudo launchctl load /Library/LaunchDaemons/org.dovecot.plist 
    EOS
  end
end
