How to "Fix" the "Copy Address" Feature in Mac OS X's Mail Client

If you're using Mac OS X 10.6, you may notice that when you right-click (or ctrl+click) on an address in Mail.app, and choose the "copy address" item from the contextual menu, when you paste that address somewhere else, the address shows up like

Matt Silver <msilver@gmail.com>

Which is fine, but if you save addresses to plain text often, and don't want to have both the email address and the name, you can fix it to behave like the Mail application did in Mac OS X 10.5.

• Quit Mail (command+q)
  
• Open up the Terminal application from /Applications/Utilities
  
• Paste the following line into the terminal window and press "Return"

  defaults write com.apple.mail AddressesIncludeNameOnPasteboard -boolean No

  
  
• Quit the Terminal application and open Mail again.

When you go to copy and paste an address, just the address should show up like this:

msilver@gmail.com

I found this from a few other blogs when trying to help an employee at work, but also discovered http://secrets.blacktree.com/ which has a WHOLE bunch of defaults you can change in a similar fashion.
