An email address identifies an email box to which email messages are delivered. This article covers modern internet email, but many earlier email systems used different address formats.
The local part of an address (before the @ sign) is case-sensitive (with the exception of postmaster@example.com). The domain part (after the @ sign) is not case-sensitive. Most organizations treat uppercase and lowercase letters in the local part as equivalent. The risk of delivery failures due to case differences can be minimized by using only lower case characters when creating new addresses.

Famous quotes containing the word address:
“Patience, to hear frivolous, impertinent, and unreasonable applications: with address enough to refuse, without offending; or, by your manner of granting, to double the obligation: dexterity enough to conceal a truth, without telling a lie: sagacity enough to read other people’s countenances: and serenity enough not to let them discover anything by yours; a seeming frankness, with a real reserve. These are the rudiments of a politician; the world must be your grammar.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
