Parsing Mail Headers

[Steven M. List]

Does anyone have a program or PERL script or... that already does parsing
of mail headers?  I have no doubt that this exists, and based on a
thread realized that a mail folder sorter could be written fairly easily
once the parsing is done.  And why reinvent the wheel, right?
