+# NOTE
+# ----
+# We explicitly specify the *home* here, allowing that a user has the
+# same mailboxes with all its alias(es).
+#
+# Fields
+# ------
+# user:(password):uid:gid:(gecos):home:(shell):extra_fields
+# * uid - override the global $mail_uid
+# * gid - override the global $mail_gid
+# * home - override the global $mail_home
+# The ()-enclosed fields are ignored by Dovecot userdb lookup.
