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/<login></code>. The default
location for mail is <code class="filename">/var/mail/<login></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.
</p></dd><dt><span class="term">
<code class="option">empty</code>

Also print message if user has no mail.

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>.

Do not set the <span class="emphasis"><em>MAIL</em></span>

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
about it.
</p></dd><dt><span class="term">

mail spool being used. This also implies "empty".
