Configure Script

The AppleScript is configured through Mail's Preferences Rules tab. Choose "Add Rule" and under "Perform the following actions" select "Run Applescript". The next drop down will give you the option to select the script to run.

The script won't appear until it's in the correct folder. Select "Open in Finder" to get to the correct folder in the Finder. You can then copy the above script that you saved to your Desktop into Mail's AppleScript folder and select it.
