An e-mail address identifies a location to which
e-mail messages can be delivered. The term "e-mail address" is also used as the formal pre-registered authoritative electronic mailing delivery site for an individual (example: an attorney's e-mail address registered for delivery of proof of service digital copies of legal pleadings). A modern
Internet e-mail address (using
SMTP or
Usenet) is a string of the form jsmith@example.com. It should be read as "jsmith at example dot com". The part before the @ sign is the local-part of the address, often the
username of the recipient, and the part after the @ sign is the domain-part which may be a host name or
domain name which can be looked up in the
Domain Name System to find the
mail transfer agent or
Mail eXchangers (MXs) accepting e-mail for that address.
