dovecot - Mar 2013 - Stability of extraction of attachment

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"?

I just forgot to remove that warning. Removed now in v2.2 (not in v2.1, because
people complain if I do unnecessary changes to example-config).

If FS supports it then let it do it. If it doesn't, sis is easier than
sis-queue since it doesn't need a cronjob. Also I'm not sure if
sis-queue makes the performance better or not (the idea being that it delays the
slowness until night when it's more quiet).
