You could try Mail::Header which is part of MailTools (but does not seem to show up on its own though :/) Which lets you maniplate the headers with relative ease. Although I do not think it has a function to return all the email addresses you could look through the relevant header fields and grab the addresses from there..

Update: It would appear that ZZamboni types faster than I do.
