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:
“Another success is the post-office, with its educating energy augmented by cheapness and guarded by a certain religious sentiment in mankind; so that the power of a wafer or a drop of wax or gluten to guard a letter, as it flies over sea over land and comes to its address as if a battalion of artillery brought it, I look upon as a fine meter of civilization.”
—Ralph Waldo Emerson (1803–1882)
