Using SENDMAIL from the SUSE LINUX Software Package, Where can the user find:
a. configuration options and setup?
b. the functions the package supports?
C. examples of use?
d. security considerations?
e. sources of information and support?
f. where releases of the package may be obtained?
Where can one become familiar with the package manager used by SUSE LINUX distribution and find out how reinstall the package from the distribution disks without utilizing the initial install process? Where can one finds how to demonstrate use, configuration and setup? What are the important features, uses, and documentation sources? The 520 points from ‘rapm’ submission was taken away from me.
