debian 3 Maildirs a weird size (4.0 K) ??

[pyka99@hotmail.com (Jim)]

Hi,

I am trying to backup my Maildir in debian (using exim & courier-imap)
but looking at the actual Maildir in the home directory (specified in
exim for it to be there) it's size is 4.0 K for the whole directory,
and inside it I can see every folder I have in that account but they
are all 4.0 K even though the account as a few hundred Megs of email
accumulated over time.

Any ideas then where the actual directory is that holds my email so I
can back it up? Any help appreciated.

Jim.
