Email remains the killer information and communications technology. Email volume shows no sign of diminishing, despite the increasing popularity of collaborative messaging tools.
Messages are exchanged between hosts using the Simple Mail Transfer Protocol with software programs called mail transfer agents, and delivered to a mail store by programs called mail delivery agents, frequently referred to as email clients.
Email clients offer a variety of features. Many email clients offer a slew of features, some stick with just the basics. At the end of the day, what is important is that you find an email client that offers what you need, it is reliable, and works well on your computer.
