+# yet, 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
+#
+# See /usr/share/doc/dovecot-common/wiki/Variables.txt for full list. Some

+# You can have private, shared and public namespaces. The only difference
+# between them is how Dovecot announces them to client via NAMESPACE

+# accessible mailboxes.
+#
+# REMEMBER: If you add any namespaces, the default namespace must be added
+# explicitly, ie. mail_location does nothing unless you have a namespace
+# without a location setting. Default namespace is simply done by having a
+# namespace with empty prefix.
