104 \name{Unified messaging}, although often used exchangeable with unified communications, is only a subset of it. It does not require real-time data transmission and is therefore only usable for asynchronous communication \citeweb{wikipedia:uc}. Unified messaging's function is basically: Receiving incoming messages from various channels, converting them into a common format, and storing them into a single memory. The stored messages can then be accessed from different devices \citeweb{wikipedia:um}. 104 \name{Unified messaging}, although often used exchangeable with unified communications, is only a subset of it.

106 The easiest way of Unified Messaging is to base it on either email and convert all input sources to email messages (as attachments for instance) and store them in the user's mail box, or use the telephone system as basis and convert text messages to speech. Both is technically possible for asynchronous communication. 106 The easiest way of Unified Messaging is to base it on either email and convert all input sources to email messages (as attachments for instance) and store them in the user's mail box, or use the telephone system as basis and convert text messages to speech.

His description of the technology ended with the humorous sentences: 108 Finally, a critical voice from \person{Jesse Freund}, who voted Unified Messaging on top of a hype list, published by \name{Wired.com} ten years ago.

190 Today's email structure is heavily dependent on email providers. This means, most people have email addresses from some provider. These can be providers that offer email accounts in addition to their regular services, for example online connections. \NAME{AOL} and \name{T\mbox{-}On\-line} for instance do so. Or specialized email providers that commonly offer free mail as well as enhanced mail services, one must pay for. Examples for email providers are \NAME{GMX}, \name{Yahoo}, and \name{Hotmail}. %fixme: check for non-breakable dash 190 Today's email structure is heavily dependent on email providers.

192 Outgoing mail is send either with the webmail client of the provider or using \name{mail user agent}s sending it to the provider for relay. Incoming mail is read with the webmail client or retrieved from the provider via \NAME{POP3} or \NAME{IMAP} to the local computer to be read using the \name{mail user agent}. This means all mail sending and receiving work is done by the provider. 192 Outgoing mail is send either with the web mail client of the provider or using \name{mail user agent}s sending it to the provider for relay.

194 The reason therefor is originated in the time when people used dial-up connections to the Internet. A mail server needs to be online to receive email. Sending mail is no problem, but receiving it is hardly possible with an \MTA\ being few time online. Internet service providers had servers running all day long connected to the Internet. So they offered email service, and they still do. 194 The reason therefor is originated in the time when people used dial-up connections to the Internet.

196 Nowadays, dial-up Internet access became rare; the majority has broadband Internet access paying a flat rate for it. Hence the time being online not affect costs anymore, even traffic is unlimited. Today it is possible to have an own mail server running at home. The technical problem remaining is the changing \NAME{IP} addresses one gets assigned every 24 hours. But this is solvable with one of the dynamic \NAME{DNS} services; they provide the mapping of a fixed domain name to the changing \NAME{IP} addresses. 196 Nowadays, dial-up Internet access became rare; the majority has broadband Internet access paying a flat rate for it.
