MailFollowup Mail Plugin

MailFollowup Mail Plugin Publisher's Description:
Adds a "Followup" item to the Message and contextual menus (and optional toolbar item) of Apple's Mail application that allows you to compose (and then send) a quoted version of the original message to all of the original recipients, keeping the To, Cc and Bcc addresses exactly as they appeared in the original message. Hawk Wings has a nice description of MailFollowup.
