Burst Digest Messages for Mac

From Andreas Amann:

This AppleScript for Mail will take one or more selected MIME digest messages (messages formatted as either multipart/digest (MIME digest) according to RFC2046 or simple digest as defined by RFC1153) and extract the individual messages from the digest message - this is especially useful if you are subscribed to a mailing list in digest format but want to reply to a single message in the digest rather than the digest message itself. The individual messages will be moved to the same mailbox as the original digest message and the temporary Import folder will be deleted (note that the root "Import" folder currently cannot be deleted due to a bug in Mail's AppleScript implementation). When running the script for the first time, the user can choose whether or not to delete the digest message upon successful extraction of the individual messages.
