You may have noticed that when copying an email address in Mail on Snow Leopard that the default format when you paste it back into another application has changed and now appears as :-

Firstname Surname <firstname@domain.com>

This is pretty annoying and to be honest it is hard to understand why Apple decided that this was a necessary change to the original Mail app behaviour. Fortunately there is a fix to restore the default behaviour. Fire up a Terminal window and copy and paste the command below to restore normality !

defaults write com.apple.mail AddressesIncludeNameOnPasteboard -bool NO
