+# Directory where mailboxes reside, _or_ name of file, relative to the
+# home directory. If you _do_ define MAIL_DIR and MAIL_FILE,
+# MAIL_DIR takes precedence.
+#
+# Essentially:
+# - MAIL_DIR defines the location of users mail spool files
+# (for mbox use) by appending the username to MAIL_DIR as defined
+# below.
+# - MAIL_FILE defines the location of the users mail spool files as the
+# fully-qualified filename obtained by prepending the user home
+# directory before $MAIL_FILE
+#
+# NOTE: This is no more used for setting up users MAIL environment variable
+# which is, starting from shadow 4.0.12-1 in Debian, entirely the
+# job of the pam_mail PAM modules
+# See default PAM configuration files provided for

+# Only used if ENCRYPT_METHOD is set to SHA256 or SHA512.
