Turn off Data Detectors in Mail.app
Among the new features Apple touted in Leopard was data detectors in Mail.app. The idea is that if somebody sends you an email with a street address in it, for example, Mail.app can detect that it's a street address and add it an Address Book contact with just a couple of clicks. Unfortunately, while the basic idea isn't bad, sometimes you just want to copy something and the data detectors simply get in the way (and leads, in my case at least, to some gratuitous cursing).
Well, Michael Tsai has found the solution with a hidden preference. All you have to do is type in (or copy and paste in) one line to the Terminal and the data detectors will be banished from Mail.app. Head on over to Tsai's post for full details and kiss the cursing goodbye.
