Not definately true.  The Mail/MIME encoding RFC's state that all headers
should be CRLF no matter what the platform.  It is open to dispute quite
whether the RFC's should still apply once the mail has finished it's journey
through the ether and has been collected from the email server by such a
tool as fetchmail.  It seems likely that Mozilla is expecting the CRLF's to
remain on the headers which would probably be true if Mozilla was collecting
the emails itself.  It is my guess that fetchmail is stripping the CR's from
the message as it retrieves it which could well be the accepted practice for
UNIX boxes, but under a cygwin text mount it should perhaps behave

This is purely speculation I've not looked at the sources, but it is
certainly true that the pop3 server should be presenting the headers with
CRLF line endings to the client.
