Architecture
The Postfix core consists of several dozen daemon programs that run in the background, each handling one specific aspect of email delivery. Examples are the SMTP server, the scheduler, the address rewriter, and the local delivery daemon. For damage-control purposes, most daemon programs run with fixed reduced privileges, and terminate voluntarily after processing a limited number of requests. Only a small number of Postfix daemons interact with users through two small "gate" programs for mail submission and for queue status information.

Famous quotes containing the word architecture:
“Art is a jealous mistress, and if a man have a genius for painting, poetry, music, architecture or philosophy, he makes a bad husband and an ill provider, and should be wise in season and not fetter himself with duties which will embitter his days and spoil him for his proper work.”
—Ralph Waldo Emerson (1803–1882)
“They can do without architecture who have no olives nor wines in the cellar.”
—Henry David Thoreau (1817–1862)
“For it is not metres, but a metre-making argument, that makes a poem,—a thought so passionate and alive, that, like the spirit of a plant or an animal, it has an architecture of its own, and adorns nature with a new thing.”
—Ralph Waldo Emerson (1803–1882)
