Hello,

We are migrating our dovecot servers from 2.1.9 to 2.1.15 (or 2.2 if 

there is a stable version soon) and maildir format to mdbox.

Looking for mdbox options I have found options:

• mail_attachment_dir

• mail_attachement_min_size

• mail_attachment_fs

• mail_attachment_hash

  but this options are described with the message:

WARNING: This feature hasn't been tested much yet. Use at your own risk.

What is the state of these options? Could I use it in a production 

environment? In case of yes, what is the best deduplicating option? Let it to the FS? Or configuring with "sis posix" or "sis-queue posix"?
