[Dovecot] Question about folder creation/delete and logging

Hello

We are working in a web based restore system for our Dovecot users. In this web form a user must log-in and after successful login can estore a deleted folder from date X. We will release it under the GPL. I have a couple of questions:

• Is there any way of Dovecot logging to write when a folder is deleted or created? We do not want to increase too much our "normal" logging level. We use Dovecot 2.0.18+mdbox+zlib
• Does anybody know of any other project to create an easy-restore for Dovecot?

Regards

Maria
