Now that email is everywhere, not only on computers but on phones and tablets, even casual technology users need to understand their email configuration options.
Not only can understanding your choices make managing your email easier, but your efficiency, privacy and security can be greatly enhanced as well.
For receiving email the most common protocol is old good old-fashioned Post Office Protocol (POP3).
Using this protocol any device can download messages from your email hosting servers. If you use multiple devices you might want to configure each device “leave mail on server” for just a few days in order to allow each device enough time to download a copy of each message. Leaving too much mail on your email server for too long can slow down your access and also exceed your email storage quota. For more on this subject, see: Should I Leave Messages On The Server?
