An e-mail address, also known as an eddress (from electronic address) or sometimes (in a technical misuse of the word), simply as one's email, identifies a location to which e-mail can be delivered. 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 a 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.
