      The pam_mail PAM module provides the "you have new mail"
      service to the user. It can be plugged into any application
      that has credential or session hooks. It gives a single message
      indicating the <span class="emphasis"><em>newness</em></span> of any mail it finds
      in the user's mail folder. This module also sets the PAM
      environment variable, <span class="emphasis"><em>MAIL</em></span>, to the
      user's mail directory.
    </p><p>
      If the mail spool file (be it <code class="filename">/var/mail/$USER</code>
      or a pathname given with the <code class="option">dir=</code> parameter) is
      a directory then pam_mail assumes it is in the
      <span class="emphasis"><em>Maildir</em></span> format.

              Look for the users' mail in an alternative location defined by
             <code class="filename">maildir/&lt;login&gt;</code>.  The default
             location for mail is <code class="filename">/var/mail/&lt;login&gt;</code>.
             Note, if the supplied
             <code class="filename">maildir</code> is prefixed by a '~', the
             directory is interpreted as indicating a file in the user's
             home directory.

              Mail directory hash depth. For example, a
              <span class="emphasis"><em>hashcount</em></span> of 2 would
              make the mail file be
              <code class="filename">/var/spool/mail/u/s/user</code>.

	      Don't print any mail information on login. This flag is
              useful to get the <span class="emphasis"><em>MAIL</em></span>
              environment variable set, but to not display any information
