Everybody knows what email is, right? In the modern business world, email has become one of our most important methods of communication, and indeed often a web hosting client considers the operation of his email more important than the website itself. Unfortunately however, most people have only a very superficial idea of how email really works, so when trouble does arise, they have no idea how to troubleshoot the problem and it takes longer to solve. Just by knowing the basics of how email works, you can give a more accurate problem description to tech support personnel and even solve some problems yourself! You might even find some new and useful features of your email that you didn't know about before.
