I want to archive oe mail

Any suggestions for a program (free if possible) which will do the following 
to my oe mail:

1 save individual folders I created in oe into individual archived folders.
2 allow the archived mail to be read (and appear) like it did when I 
received it.
3 allow me to open each archived mail in an oe like environment.
4 archived mail to contain the original date (header info) and be listed in 
the original order (usually by date received.)
5 the archiving operation to semi automated so that I do not have to 
manually open each and every subfolder to get the mail archived (I have 
many, many folders.)
