This subchapter looks at sendmail, a UNIX/Linux utility.
sendmail is used to send email.
In 1975 the Sendmail email system was added to the BSD version of UNIX. Because email was built into the operating system, email was the method UNIX used for sending notifications to the system administrator of system status, reports, problems, etc.
Each version of UNIX has its own variation of sendmail, but the default installation almost always works correctly without modification. A system administrator rarely needs to know how to set-up or modify sendmail.
Coding example: I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).
View music player in action: www.musicinpublic.com/.
Create your own copy from the original source code/ (presented for learning programming).
