     [SNIP]
All three remarks fit exactly in the Mail::Box structure.  Deletes only
take place when a mail-box is written, which is called automatically
when the folder is closed explicitly (by calling close()) or
implicitly (by dropping the folder reference)  The write may have to
re-establish connection.

I don't think so.  I believe that this must be part of applications
which use Mail::Box, unless it is practical for many users.  Keep in
mind that the target of Mail::Box is to become a common interface
to many kinds of folders and messages as 'back-end' for real
applications.

Maybe you can do a first rougth implementation of a POP folder, and
we can discuss what can be simplified and what must be added to the
Mail::Box overall structure to satisfy the needs of supporting POP.
It seems not too complicated.  Let's try to keep it that way!
