	207	# yet, so you should explicitly tell Dovecot the full location.
	208	#
	209	# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
	210	# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
	211	# kept. This is called the "root mail directory", and it must be the first
	212	# path given in the mail_location setting.
	213	#
	214	# There are a few special variables you can use, eg.:
	215	#
	216	# %u - username
	217	# %n - user part in user@domain, same as %u if there's no domain
	218	# %d - domain part in user@domain, empty if there's no domain
	219	# %h - home directory

	238	# mailboxes that are managed by sysadmin. If you create any shared or public
	239	# namespaces you'll typically want to enable ACL plugin also, otherwise all
	240	# users can access all the shared mailboxes, assuming they have permissions
	241	# on filesystem level to do so.
	242	#
	243	# REMEMBER: If you add any namespaces, the default namespace must be added
	244	# explicitly, ie. mail_location does nothing unless you have a namespace

	909	# By adding master=yes setting inside a passdb you make the passdb a list

	913	# master passdb. <doc/wiki/Authentication.MasterUsers.txt>
	914
	915	# Users can be temporarily disabled by adding a passdb with deny=yes.
	916	# If the user is found from that database, authentication will fail.

	929	# database (passwd usually), you can use static userdb.

	942	#
	943	# max_requests specifies how many PAM lookups to do in one process before

	949	# because PAM modules can do all kinds of checks besides checking password,
	950	# such as checking IP address. Dovecot can't know about these checks
	951	# without some help. cache_key is simply a list of variables (see
	952	# doc/wiki/Variables.txt) which must match for the cached data to be used.
	953	# Here are some examples:
	954	# %u - Username must match. Probably sufficient for most uses.
	955	# %u%r - Username and remote IP address must match.
	956	# %u%s - Username and service (ie. IMAP, POP3) must match.
	957	#
