PAM_MAIL(8) Linux-PAM Manual PAM_MAIL(8)

NAME

pam_mail - Inform about available mail

SYNOPSIS

pam_mail.so [close] [debug] [dir= maildir] [empty] [hash=count] [noenv] [nopen] [quiet] [standard]

DESCRIPTION

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.

OPTIONS

close
Indicate if the user has any mail also on logout.
debug
Print debug information.
dir=maildir
Look for the users' 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.
empty
Also print message if user has no mail.
hash=count
Mail directory hash depth. For example, a hashcount of 2 would make the mail file be /var/spool/mail/u/s/user.
noenv
Do not set the MAIL environment variable.
nopen
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.
quiet
Only report when there is new mail.
standard
Old style "You have..." format which doesn't show the mail spool being used. This also implies "empty".

MODULE TYPES PROVIDED

The session and auth (on establishment and deletion of credentials) module types are provided.

RETURN VALUES

PAM_BUF_ERR
Memory buffer error.
PAM_SERVICE_ERR
Badly formed arguments.
PAM_SUCCESS

User not known.
