[Evolution] How can I prevent Evolution from storing IMAP mails in filesystem?

[Thomas Broda <thomas broda org>]

Hi,

I'm using Evolution 3.2.1 on Ubuntu 11.10 to access my IMAP server.

The "automatically synchronize remote mails locally" checkbox under
"mail accounts" -> "receiving options" is not active. However, Evolution
obviously creates an mbox file containg every read message under
~/.local/share/evolution/mail/foo/folders/INBOX.

Since I'm paranoid, I dont't want my mails being stored in the local
filesystem. Is there any way to prevent Evolution from doing this?

I've installed the following packages:

evolution - 3.2.1-0ubuntu1
evolution-common - 3.2.1-0ubuntu1
evolution-data-server - 3.2.1-0ubuntu1
evolution-data-server-common - 3.2.1-0ubuntu1
