MailRecent adds "Copy to Recent," "Move to Recent," and "Go to Recent" menu items to Apple's Mail application.
These menu items contain dynamically-updated lists of recently used mailboxes. The number of mailboxes kept in the list is determined by the "Recent Items" setting in the General panel of the OS X System Preferences.
