DESCRIPTION</h3></div></div></div><p> 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. </p></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="sag-pam_mail-options"></a>6.19.2.
