Quoting Henrique de Moraes Holschuh (hmh at debian.org):

That seems to be the problem. We certainly need to remove the "noenv"
directive from the pam_mail line in the default login PAM
configuration file:

# Prints the status of the user's mailbox upon succesful login
# (Replaces the `MAIL_CHECK_ENAB' option from login.defs). You
# can also enable a MAIL environment variable from here, but it
# is better handled by /etc/login.defs, since userdel also uses
# it to make sure that removing a user, also removes their mail
# spool file.
