subjecREplace is a plug in for Apple Mail.app. It replaces annoying AW:, WG:, SV: and so on coming from Microsoft Outlook in Apple Mail. Thus long chains of Re: AW: Re: AW: can be avoided. Of course can u do it manually, but why?
*Type in terminal:
defaults write com.apple.mail EnableBundles 1 defaults write com.apple.mail BundleCompatibilityVersion 4
*Copy subjectREplace.mailbundle to ~/Library/Mail/Bundles
Add more abbreviations to be replaced
Open ~/Library/Mail/Bundles/subjectREplace.mailbundle/Contents/Info.plist with the Property List Editor and add childs to StringsToREplace or StringsToReplaceFWD like AW:, SV:, WG: (note the : ) respectively.
