E-Mail Address
General information
An e-mail address identifies a location to which e-mail can be delivered. A modern Internet e-mail address (using SMTP) 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 exchange servers accepting e-mail for that address.
The domain name is often that of the of the e-mail service, such as Microsoft's Hotmail or Google's Gmail it could also be the domain name of the company that the recipient represents or even the domain of the recipient's personal site.
Earlier forms of e-mail address included the somewhat verbose notation required by X.400, and the UUCP "bang path" notation, in which the address was given in the form of a sequence of computers through which the message should be relayed. This latter was in wide use for several years, but was superseded by the generally more convenient SMTP form.
Addresses found in the headers of e-mail should not be considered authoritative, because SMTP has no mechanism for authentication. Forged e-mail addresses are often seen in spam and in phishing and similar scams, leading to several initiatives, such as Sender ID, which aim to make such forgeries easier to spot. The most reliable method of authentication, however, is to require that messages be digitally signed.
Limitations
The format of Internet e-mail addresses is defined in RFC 2822, which permits only a subset of ASCII characters in e-mail addresses. RFC 1642, however, defines UTF-7, a way of encoding all Unicode characters using only characters permitted in e-mail; e-mail addresses using this standard are most commonly seen in Asia and not widely used in Europe or North America.
As defined in RFC 2821, the local-part of an e-mail address allows up
E-Mail Address
Would be nice for someone to find a list of government e-mail-for-all initiatives or more of the cultural stuff, rather than just adding to the technical details.
A note vis-a-vis allowed characters - despite me accidentally adding a period to the excluded characters list, the rest are from the RFC, so should be correct. If you see different it's because the standard is being broken.
The Need for E-mail
I cut this section, then User:IanM restored it. I'm cutting it again because it still has many errors. I don't object to something like this being in the article, but it should be correct.
:Having your own e-mail address is considered an essential part of life in cyberspace and is required for almost everything other than viewing pages. Making online purchases, subscribing to paid content, posting in web logs or Internet forums, participating in Usenet newsgroups and many other tasks will require a valid e-mail address. Despite once being considered part of "geek culture", not having an e-mail address can seriously disadvantage a person. For this reason, many governments in modern countries are undertaking initiatives to give e-mail addresses to public servants and school children.
None of the listed activities ''require'' an e-mail address. ''Most'' online retailers and ''some'' web sites require you to have an e-mail address in order to sign up for their services. But some retailers and most web sites don't. For example, you don't need an e-mail address to edit Wikipedia. So this needs to be rewritten with specifics. How exactly not having an e-mail address disadvantage a person? Which governments are untaking which initiatives? Gdr 10:20, 2004 Jul 9 (UTC)
Maybe "Making online purchases..." should be replaced with "In many cases making online purchases..."? Paul Carpenter 14:59, 23 Apr 2005 (UTC)
