An email consists of three vital components: the envelope, the header(s), and the body of the message. The envelope is something that an email user will never see since it is part of the internal process by which an email is routed. The body is the part that we always see as it is the actual content of the message contained in the email. The header(s), the third component of an email, is perhaps a little more difficult to explain, though it is arguably the most interesting part of an email. Header In an e-mail, the body (content text) is always preceded by header lines that identify particular routing information of the message, including the sender, recipient, date and subject. Some headers are mandatory, such as the FROM, TO and DATE headers. Others are optional, but very commonly used, such as SUBJECT and CC. Other headers include the sending time stamps and the receiving time stamps of all mail transfer agents that have received and sent the message. In other words, any time ...

Would you like to track down (or trace) where an email that you received came from? This Trace Email tool can help you do precisely that.

               Image caption Tor Messenger can allow encrypted communications even to services blocked by the user's own country A new chat tool has been launched in an effort to improve the security of online messaging. Tor Messenger allows users to chat over the Tor (The Onion Router) network in a way which hides the location of participants. It means that the contents of messages will only be visible to the participants. The service will also work with platforms like Facebook even in countries where they are banned. The tool is currently in beta and will undergo security tests. Users wishing to remain anonymous or access chat clients blocked in their own country could use Tor Messenger to chat via services like Facebook Chat, Google Talk, Twitter, Yahoo and Internet Relay Chat. The program does not communicate via what's often called the "dark web", a collection of hidden w...

YouTube is to launch a subscription service offering original, exclusive videos - including feature-length films starring high-profile vloggers Initially only available in the US, YouTube Red will cost $9.99 (£6.50) a month and have no adverts. PewDiePie, Rooster Teeth and Lilly Singh are among the well-known names involved. Analysts suggested it could be difficult to turn millions of fans who expect free access to pay up. "It's great to see YouTube offer an alternative to an ad-only model," said Brian Blau, an analyst with Gartner. "Consumers want choice and options." "But pay walls haven't always done well and uptake depends on how users balance the attractiveness of the exclusive content and the pain of sitting through lots of ads."

Image copyright PA Facebook has indexed almost two trillion posts put on the site by its members to make it easier to find them. The change means that many older posts will now be added to results when people search for news or information. The move is being seen as part of Facebook's attempts to keep people on the site rather than go elsewhere to keep up to date with events. It said options were available for people that did not want their older posts to be more widely accessible. Bigger audience Tom Stocky, Facebook's head of search, said in a blog post that many people already turned to Facebook when trying to find out how friends and family were reacting to world events. About 1.5 billion searches are carried out on Facebook every day, he said. The changes that Facebook has introduced will mean members of the social network will now also see posts by strangers alongside those from news organisations and people closest to them. "Sear...

Chances are you have a Wi-Fi network at home, or live close to one (or more) that tantalizingly pop up in a list whenever you boot up the laptop. The problem is, if there's a lock next to the name, that indicates security for the Wi-Fi network is turned on. Without the password or passphrase, you're not going to get access to that network, or that sweet, sweet Internet that goes with it. Perhaps you forgot the password on your own network, or don't have neighbors willing to share the Wi-Fi goodness. You could just go to a café and buy a latte and use the "free" Wi-Fi there. Download an app for your phone like WiFi-Map , and you'll have a list of over 2 million hotspots with free Wi-Fi for the taking (including some passwords for locked Wi-Fi connections, if they're shared by any of the app's 7 million users). But there are other ways to get back on the wireless, though some of them require such extreme patience and waiting, that café idea is going t...
