MailFollowup Mail Plugin

The MailFollowUp Mail Plugin adds a "Follow Up" 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 it, and Dan Frakes wrote about it in January of 2007.

New in version 1.5.3

Updated for Mac OS X 10.8. FIXED: Resolved issue with "Follow-Up Subject Prefix" not working
