This file describe shortly the changes between openwebmail 2.01 and openwebmail
2.01 with storage modules.

The following parameters have been added to etc/openwebmail.conf*

storage_module => The the storage module used in openwebmail. Actually only 2
are available. The default is storage_mbox.pl for the legacy mbox format.
storage_maildir.pl is for maildir storage.

enable_filter => Enable the traditional openwebmail filters. I add this because
I need to disable them when using the filters of the pll project
(http://pll.sourceforge.net/). Default is enable.


Code changes:

All accessess to mail folders and messages have been removed from the main code
and put in the storage modules.

All folder lock have been changed 
from:
	filelock($folderfile, LOCK_XXX);
to:
	folderfilelock($folderfile, LOCK_XXX);

because not all storage need locking (maildir doesn't).
