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 newness of
any mail it finds in the user's mail folder. This module also sets
the PAM environment variable, MAIL, to the user's mail directory.
If the mail spool file (be it /var/mail/$USER or a pathname given
with the dir= parameter) is a directory then pam_mail assumes it is
in the Maildir format.
Indicate if the user has any mail also on logout.
Print debug information.
Look for the user's mail in an alternative location defined by
maildir/<login>. The default location for mail is
/var/mail/<login>. Note, if the supplied maildir is prefixed by a
'~', the directory is interpreted as indicating a file in the
user's home directory.
Also print message if user has no mail.
Mail directory hash depth. For example, a hashcount of 2 would
make the mail file be /var/spool/mail/u/s/user.
Do not set the MAIL environment variable.
Don't print any mail information on login. This flag is useful to
get the MAIL environment variable set, but to not display any
information about it.
Only report when there is new mail.
Old style "You have..." format which doesn't show the mail spool
being used. This also implies "empty".
