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.

Just a note:

This isn't the same as the common "mbox" format that UNIX mailers tend to
use.  mbox is a flat file of email, and deleting an email removes it from
the file.  What Thunderbird is doing is different.

Outlook does something very similar, at least through Outlook 2000.

Yes, but he said mbx-format, not mbox-format. mbx-format is a different
format, and also comes from the unix-world. Very ancient too.

Just for further exemplification, EXIM (the MTA) supports MBOX format,
maildir format, and mbx format. See:

http://www.exim.org/exim-html-4.40/doc/html/spec_26.html#IX1986

About mbx-format implementation on EXIM 4.40.

On the other hand, I doubt it is the exactly the same format used by
Thunderbird.
