.PP

\fBMAIL_DIR\fR (string)

The mail spool directory\&. This is needed to manipulate the mailbox when its corresponding user account is modified or deleted\&. If not specified, a compile\-time default is used\&. The parameter CREATE_MAIL_SPOOL in

The

The default value is 0, meaning that there are no limits in the number of members in a group\&.

This feature (split group) permits to limit the length of lines in the group file\&. This is useful to make sure that lines for NIS groups are not larger than 1024 characters\&.

If you need to enforce such limit, you can use 25\&.
