today face a slippery topic ... our beloved e-mail boxes. All now have at least one: the e-mail in a few years it has become an essential business tool. But nobody has ever wondered what happens to our messages once delivered to the provider? What is the difference between the boxes "paid" and unpaid? And, above all, because some providers do you pay for a service that others offer free or really ridiculous figures?
try to distinguish the various types of services:
- Free services: provided by Google (with Gmail), Free, Telecom Italy, etc. ...
- Services fee: provided by small / medium / large providers
- Services DIY "provided by the users themselves (most geeks) who have the ability to have a mail server in house.
X uses a free service, Y uses a paid service, the two exchanged a daily average of N messages.
One day the spell is broken and the problems begin: the e-mail not arriving at their destination. What happened? Y
calls his e-mail service provider who, being obliged to answer the phone and track email depart and arrive on their servers, provide all relevant information: time and date of shipment or arrival of message delivery to the recipient's server or to your customer, etc. ...
X, however, after a long wait on the phone receives the comforting news, on an answering machine that the mail server of your provider for some days they do not want to know about your work ... and as the service is free, answering the phone is an option.
Example, instead deliberately provocative tone, not far from the reality of things.
In the next chapter we'll talk about filters Spam and how they are maintained by different providers.
