Subject: thunderbird privacy...
Tunderbird uses for every folder a pseudo-database with a big data-file
contining every mail and a corresponding index-file (*.msf, for
thunderbird) - just like every harddisk does. if you delete a message,
it gets deleted only in the index - this is fast and you won't see the
msg anymore in your app.
this mbx-format is an ancient, but especially in the unix-world still
very common format to store emails.
to have thunderbird delete your messages in the data-file, use "compact
folders". you may automate this to some extent in your settings
(advanced, diskspace)
you do have the same problem in almost every mailer, harddisk, database,
etc (even in winword!), regardless of the used os, application or format
- your deleted data is still stored until you "compact", "defragment" or
rebuild your data-structures.
hope this helps,
tom
