Hi again,
I have been thinking more of how people store mail on the server.
I have another space saving idea.
I beleive many people file their sent mail somewhere, I know I file it
on the server in a folder named sent. Mozilla mail copies the mail
with imap to the sent mail folder.
Now there are two identical messageblock data on the server (if the
mail was internal). One that belong to the recipient(s) and one that
belongs to the sender.
Still thinking of splitting the messageblks in two pieces
If we added a checksum record to the messageblks table we could easily
find duplicate blocks and replace them.
I was thinking of some kind low priority process that operates on the
database when it is not that busy, which calculates a checksum and
removes duplicate message data.
But there is still the question is it worth the effort?
I beleive that making the database layout change and corresponding
code changes to make it possible to share message data between users
is not that difficult. You will still get 1000 copies of the same
message sent to 1000 users.
Doing the actual storing of only one message block is a much bigger
change, that could be done in a later release.

Hi all,
Roel is currently planning the implementation of public folders as
next big thing. This will indeed require changes to the original
dbmail database layout. We'll keep you all informed!

If the attempt to replace Exchange Server is truly serious, public
folders must be implemented in some form. Some organizations LIVE by
their public folders, which prevents them from even considering
non-Microsoft solutions.
