/usr/lib/mh/conflict [ -help ] [ -mail name ] [ -search directory ] [ aliasfiles ... ]
The conflict program checks to see if the interface between MH and transport system is in good shape. It also checks for maildrops in /usr/spool/mail which do not belong to a valid user. It assumes that no user name will start with a dot (.) and thus ignores files in /usr/spool/mail which begin with a dot.
The conflict program checks the entries in the specified alias files. It parses the entries in the same way that post would, and outputs any errors which it finds. The program can be used to check the entries in a user's personal alias file, or in the system alias file, /usr/lib/mh/MailAliases. If no alias file is specified, conflict checks the system alias file.
The conflict program also checks the /etc/group file for entries which do not belong to a valid user, and for users who do not have a valid group number. In addition, duplicate users and groups are noted.
The conflict program should be run under cron, or whenever system accounting takes place.
