I'm going to guess that your desktop is trying to deliver mail to 
user at 192.168.1.65 and your laptop is saying that thats not one of the 
destinations it accepts mail for and it disallows relaying. 

If you do a 'postqueue -p' on your desktop it should show you all 
messages that are queued up and the reason they are.  To fix that 
problem you will have to use a name in mydestinations in your main.cf to 
call your laptop.  For instance, if mydestinations contains laptop, you 
should instead have the following for your transport
laptop smtp:[laptop]

Then you will want to have an entry for laptop in /etc/hosts, which I 
think you already have.  The important part is that what is in between 
the brackets in your transport file on desktop matches something in 
mydestinations on your laptop.
