It +can be plugged into any application that has credential hooks. It gives a +single message indicating the <em/newness/ of any mail it finds in the +user's mail folder. This module also sets the <bf/Linux-PAM/ +environment variable, <tt/MAIL/, to the user's mail directory. + +<p> +The behavior of this module can be modified with one of the following +flags: + +<p> +<itemize> +<item><tt/debug/ +- write more information to <tt/syslog(3)/. + +<item><tt/dir=/<em/pathname/ +- look for the users' mail in an alternative directory given by +<em/pathname/. The default location for mail is +<tt>/var/spool/mail</tt>. Note, if the supplied <em/pathname/ is +prefixed by a `<tt/˜/', the directory is interpreted as +indicating a file in the user's home directory. + +<item><tt/nopen/ +- instruct the module to <em/not/ print any mail information when the +user's credentials are acquired. This flag is useful to get the <tt/MAIL/ +environment variable set, but to not display any information about it. + +<item><tt/close/ +- instruct the module to indicate if the user has any mail at the as +the user's credentials are revoked. + +<item><tt/noenv/ +- do not set the <tt/MAIL/ environment variable. + +<item><tt/empty/ +- indicate that the user's mail directory is empty if this is found to +be the case. + +<item><tt/hash=/<em/hashcount/ +- mail directory hash depth. For example, a <em/hashcount/ of 2 would +make the mailfile be <tt>/var/spool/mail/u/s/user</tt>. + +<item><tt/standard/ +- old style "You have..." format which doesn't show the mail spool being used. + this also implies "empty" + +<item><tt/quiet/ +- only report when there is new mail. + +</itemize> + +<tag><bf>Examples/suggested usage:</bf></tag> + +This module can be used to indicate that the user has new mail when +they <em/login/ to the system. Here is a sample entry for your +<tt>/etc/pam.conf</tt> file: +<tscreen> +<verb> +# +# do we have any mail? +# +login session optional pam_mail.so +</verb> +</tscreen> + +<p> +Note, some applications may perform this function themselves. In such +cases, this module is not necessary. + +</descrip> + +<sect2>Authentication compent + +<p> +Then authentication companent works the same as the session component, +expect that everything is done during the pam_setcred() phase. + +<!-- +End of sgml insert for this module. +--> |
