Form results sent to different emails
Here's how I did it in Drupal 7, without the use of any other add-on modules:


Add a select box to the form.
In the select box options field, add your info in this format:  


  email-1@address.com|Select Option 1
  
  email-2@address.com|Select Option 2
  
  email-3@address.com|Select Option 3

Save your form, then click on the "Emails" sub-tab of the "Webform" primary tab.
Choose "Component Value > The name of the field you created in step 1". Click "Add".
Adjust your settings as needed on the following page, and you're done! The webform will now send an email to the address associated with the choice selected in the select box.
