-# tries to find the mailboxes automatically. This won't work if the user
-# doesn't yet have any mail, so you should explicitly tell Dovecot the full
-# location.
-#
-# If you're using mbox, giving a path to the INBOX file (eg. /var/mail/%u)
-# isn't enough. You'll also need to tell Dovecot where the other mailboxes are
-# kept. This is called the "root mail directory", and it must be the first
-# path given in the mail_location setting.
-#
-# There are a few special variables you can use, eg.:
-#
-# %u - username
-# %n - user part in user@domain, same as %u if there's no domain
-# %d - domain part in user@domain, empty if there's no domain
-# %h - home directory

-# mail_location = maildir:~/Maildir
-# mail_location = mbox:~/mail:INBOX=/var/mail/%u
-# mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
-#

-# ian: commented out default below
-# layout=fs makes it be maildir instead of maildir++.
-# gnus seems to have no option for maildir++, and does not
-# see folders, which are .folder in maildir++.
-# Without INBOX setting, the cur/tmp/new folders would go
-# in /m/md and not be seen by gnus.

-# If you need to set multiple mailbox locations or want to change default
-# namespace settings, you can do it by defining namespace sections.
-#
-# You can have private, shared and public namespaces. Private namespaces
-# are for user's personal mails. Shared namespaces are for accessing other
-# users' mailboxes that have been shared. Public namespaces are for shared
-# mailboxes that are managed by sysadmin. If you create any shared or public
-# namespaces you'll typically want to enable ACL plugin also, otherwise all
-# users can access all the shared mailboxes, assuming they have permissions
-# on filesystem level to do so.

-# You can use multiple locking methods; if you do the order they're declared
-# in is important to avoid deadlocks if other MTAs/MUAs are using multiple
-# locking methods as well. Some operating systems don't allow using some of
