Best Design/Order/Layout For Mailing Address Form

Is there any standards out there when it comes to a mailing address form? I need to collect the following fields:

  • address line 1
  • address line 2
  • city
  • postal code (or zip)
  • province(or state)
  • country

The country and province will be drop downs. (the province one being dependant on the country)

so my question is: is it better to have the fields in a similar layout to a standard mailing form: ie: 

address line 1    
address line 2    
city   province   postal code
country

or in a more logical order like:

address line 1    
address line 2    
city   postal code    
country province
