Mail transfer agents include sendmail, smail, qmail, and exim Wrong amount of info in install process some provide too little information, some too much
9
Deficiencies of Linux Most installations presume full-time network and ethernet Locations of help not obvious System administration difficult for non- UNIX users Lack of commercial applications Lack of hardware vendor support Lack of traditional customer support

Conclusion Linux is a multi-tasking and reliable operating system. Linux increased its market share 212% in 1998 and then increased its share 156% in 1999( this number only reflects measurable copies) Can a world-class free end-user operating system be put together right now? Of course, it can.
