parsing email headers is a complex beast. If you know how some Perl, you can try this http://search.cpan.org/~rjbs/Email-Folder-0.855/lib/Email/Folder.pm

Actually making a script to parse *.eml files and extract the From: and To: headers but it turns out some email headers have their names enclosed in quotes like "Noel Martin Llevares" <noelmartin@...> but some doesn't have. I'm having a hard time making a generalized parser.

Right now, I'm thinking at looking for Python or Perl modules that can do that. I'm looking at http://www.chilkatsoft.com/python.asp right now.
