\fBpam_mail\&.so\fR [close] [debug] [dir=\fImaildir\fR] [empty] [hash=\fIcount\fR] [noenv] [nopen] [quiet] [standard]
.SH "DESCRIPTION"
.PP
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
\fInewness\fR
of any mail it finds in the user\*(Aqs mail folder\&. This module also sets the PAM environment variable,
\fBMAIL\fR, to the user\*(Aqs mail directory\&.
.PP
If the mail spool file (be it
/var/mail/$USER
or a pathname given with the
\fBdir=\fR
parameter) is a directory then pam_mail assumes it is in the
\fIMaildir\fR
format\&.
