When you receive an email, it sits in your "INBOX" on your email provider's servers. If you wish to view this email message you must access this folder. There are several ways of doing this: a web-based interface known as "WebMail", via a program such as Microsoft Outlook or Thunderbird running on your personal computer, or via an App running on a mobile device such as an Android or an iPhone. In order for the email program or App to talk to your email provider's servers and retrieve your email messages, your device/computer and their server must communicate and "speak the same language" so that they can understand each other.
Two common "languages" that email servers understand include the "Internet Message Access Protocol" (IMAP) and the "Post Office Protocol" version 3 (i.e. "POP", "POP3" or "POP 3"). They may also understand Microsoft ActiveSync for mobile access.
POP is intended to be used in situations where you wish to connect to your email provider's servers periodically and download all of your new email to your computer or device. This has the following advantages:

LuxSci provides Secure POP mail services (as well as IMAP, WebMail, and SMTP services) to its email hosting users.
Using LuxSci's POP mail services, you can download your email at any time using your favorite email programs from anywhere in the world, so long as you have an Internet connection. LuxSci has step-by-step online instructions for configuring your email programs for use with its services, so it is quick and easy to get setup.
LuxSci's POP service is secure — POP connects over SSL or TLS. Using SSL or TLS, your username, password, and message contents are encrypted so that no one can "eavesdrop" on this information as it travels between LuxSci's servers and your personal computer.
LuxSci provides multiple "ports" for POP connections to help our users with difficulty connecting to our servers due to firewalls blocking the usual ports. In addition to the standard ports, users may optionally connect to their LuxSci secure POP service using port 2995.
LuxSci's POP server also supports the "UIDPlus" extension to enable your POP email client to perform its operations in a faster and more efficient manner.
