What is the format of those simple folders -- are they in mbox format by any 
chance?

(I am a fervent user of both pop3 and mbox folders, and for lots of reasons 
(including some software that I've developed and am continuing to develop 
(using mbox files as the storage protocol) don't expect to ever willingly give 
up either.)
